Almost anything and everything, really.
Stress (hormones), diet, major mental or physical changes, fibroids, cysts, time period following miscarriages, sooooo many things
even after pregnancy, periods are trying to get back to normal after not having one for 9 months. it’s normal to have irregular periods after a baby! i still have irregular periods and my son is about to be 2 in november!

Can take a year for periods to get back to normal after baby and breastfeeding can stop them
Because you just had a baby and it takes a while for things to get back to their new normal.

Go see a medical doctor, or the closest thing to one you can find 
Good luck
hormones are still out of wack, don’t expect things to be normal.
It takes time after birth for your body to regulate- that’s why they say no sex if ya don’t want another right away bc there’s no telling when you will ovulate and regulate
Nothing to worry about…it takes 6 to 12 months for your period to come back or get back go normal bit you should use protection cause you can get pregnant again.
After a baby your cycle has to adjust.
My 2nd didn’t show up on a test for several weeks after he should have. Also, I’ve had one period since I had my 2.5 y/o. I wasn’t on birth control for the first 2 years. I was fairly regular before that. But, be careful because I ended up with a surprise pandemic baby I didn’t even think the system was working enough to be able to do that lol
It took me almost 2 years to get a period regular again after I had my son
I have PCOS and have gone years without a period. I would talk to your doctor about it because there are several different possibilities.
Pcos, endometriosis, cysts, growths, hormone fluctuating due to other illnesses, stress.
Breastfeeding.
Just got body going back to normal after having a baby.
Go to a Dr.
It definitely isn’t caused by a vaccine.

Chemical pregnancy, my daughter had this
I was in the same boat and found out I was expecting again. Go see a Dr.
If you’re breastfeeding they’ll be crazy. I had my baby four months ago and my hormones are INSANE. Last two months I’ve been five days late each time and had a lot of pregnancy symptoms but never were. Hormomes are crazy after baby

1.) If your breastfeeding/pumping that might delay/stop it you should get it again once you stop, also hormones, stress, etc.

Are you breastfeeding? That affects periods… with my first I nursed her til she was 23months old, I didn’t get a period at all and found out I was pregnant when I was 4/5ish months along with my middle child… than with her I didn’t get a period til she was 8months old. With my third I didn’t get one til he was 10months old.
If u r breastfeeding, that will do it

If you’re breastfeeding that can cause missed periods. Stress also has tendency to interfere with your cycle. Just go to your Gyno and explain what’s going on. There’s a chance you may be welcoming baby number 2 in 6ish months too.

I know from personal experience that no period does Not mean, no ovulation, if you aren’t trying to get pregnant, you might want to start using birth control. I had 1 period after my 1st born, baby number 2 came 18 months after baby number 1

If you are breastfeeding that could be it. Also hormone changes and stress of a newborn…

You could have developed PCOS, endometriosis; you can have a cyst, stress can cause you to miss your period.
You need to try a blood test you can be pregnant and the other test show negative
Are you breast feeding? That can keep them at bay as well.

Could be your hormones are still messed up so your not having a period. If your not having regular periods then your probably not ovulating to get pregnant.
Stress can cause it. Also, I’ve heard if you are breastfeeding, that may delay your period after birth
Hmmm it could maybe be your body still adjusting to just having a baby? I know it takes quite a while for your body to return to normal after having a baby so that could be it. Or if you go for a check up to your OBGYN soon this could be something to bring up.
Are you breastfeeding? I didn’t have a period when I breastfed.

If you breast feed it can cause you to not have or skip periods… also hormones could just be off or you may have cysts on your ovaries … lots of different things
For me, it’s taken a while after I’ve had a baby for my periods to regulate. You can still get pregnant though. So be careful.

Your doctor should of let you know it can take a long time for periods to return to normal after you had the baby. If you’re nursing it can take longer too. Stress. Hormones. PCOS. Alot of things could be affecting it, I’d check with your doctor if it’s concerning you.
You just had a baby it can take up to I have heard 2 years to return to normal/regular after having a baby it doesn’t always take that long but it can. There are many other things that can cause it too. Definitely wouldn’t hurt to go talk to your obgyn they can help rule things out.

Go to the doctor and discuss your issues. Also have her do bloodwork to test for a pregnancy. I’ve known people yo never test positive on a pregnancy test but it will show up in bloodwork and an ultrasound.

Update to all the questions. I’m not on birth control. I breastfed for 2 months when she was first born. I had a period after that. So I’m not sure why it’s not coming back. I was spotting about a week ago for one day. Very light colored brown. I also have a cyst on my ovaries. Dr never said nothing else about it tho. I’ve been cramping lately no period tho.

I had 6 months of negative tests including blood work and I was pregnant. I found out 8 weeks before I had her.
Stress, changes in weight, medications, breastfeeding, cysts, and many many mite things can cause such issues even the covid vaccine can cause period issues. Go to ca doctor better to ask a trained professional than ask people who don’t know your medical history.

with my first baby, I got my period back at 3 months PP and then not again until 7 months PP. I was also exclusively breastfeeding.
my second baby is 3 months and I just had my first period last week and it was very light. so we’ll see if it shows up again next month or if it stays away for a few months again?!
Maybe since the pregnancy the period is thrown off? But like other comments are saying go ahead and see a obgyn to be sure
After my youngest it’s taken over a year for my period to regulate. It went from skipping months, to 2x a month to finally once a month. 
Stress will do that!!!

Not to scare any1 but only because I know from experience, ovarian cancer also mimics pregnancy symptoms aswel and although some think that a smear test detects this it doesnt there is no test for ovarian cancer other than a blood test call ca125 which is not done routinely x
