Need help!

So I haven’t had my period in two years and some months, I took out my IUD and my cycle was all messed up but a month ago I finally got my period. It lasted like a day or two. This month I got my period as predicted, it lasted like 3 days then came back the following week heavy and I’m getting I guess a full 5 day cycle witch is normal for me.... question is I tracked my 3day period and now that I’m on it again it pushed my ovulation back would I still test or wait for my period to end? Help please. . . .
