Extended period and ovulation

Brittany

Soo I had a surgery to take out a polyp, one lonely poc that she said is from a past MC and I started to have normal periods until July. Then I went from july till early November with no period. Now it’s going into week 3 and finally coming to an end, I hope, (I get it, that was a lot to get through) but does that mean my ovulation is totally screwed or do I count normal still??

I hate not having a normal cycle sometimes.
