Has this happened to anyone years after having a tubal?

Could you post this question for me? I’m 35, almost 36, I had a tubal at 22, which I found out were false clips. I also had an ablation in 2012. Well, this month, the march has been odd. My last normal period date was 2/28/2021 (since ablation, my periods are only spotting a couple of days). Since then, march 8-13, I spotted again longer than normal off, and on those days, I was also was sick during this time with headache and vomiting. Pinkish brown spotting, Then craved salads for a week. Now it’s March 21… And I’m spotting again. First, it was a dark red, then changed to now brown but also clear discharge with it. I don’t really think I’m pregnant, but I’m curious if anyone else has had this. Also, I used to like the taste of honey mustard and sour cream, and now both taste gross to me. Any advice? Also, to add, today on march 21 I’ve also had a bit of nausea and lightheadedness with a slight headache
