Has anyone had a period and ended up pregnant right after? Like you just got pregnant to close to your period and had it then was pregnant? We tried all month then I started and I just wanna be sure that I’m not pregnant and not know or something
Pretty sure that’s not even possible. You wouldn’t get your period if you were pregnant 
you could have implantation bleeding although you should be able to tell the difference between that and your normal period.
If you aren’t sure , take a test. Normal healthy couples can take up to a year to conceive. It’s not unheard of to have a period and be pregnant, but usually a period means you aren’t pregnant.
Look into the family planning method (not rhythm method). You learn to read Temps and your body to accurately predict ovulation.
I avoided pregnancy for over 10 years using it.
I bleed for 3 weeks from 4wk-7wk they called it implantation bleeding it was pink spotting but you ovulate right after your period usually but everyone is different use a tracker
I had sex 1-2 days off my period and was pregnant
