Hiiii ladies!

I’m seriously confused so maybe you can help!!

I have been on birth control for 4 years and I stopped in august of ‘20 so I could get pregnant this year. My period was normal until December when it never came and I took plenty of tests and wasn’t pregnant but the week after my expected period I took an ovulation test and I was ovulating. We actually tried then to get pregnant but then the next week I started my period.

I tracked my ovulation again, two weeks after that, and we tried again. I was supposed to start my period a week ago and I’ve taken like 10 pregnancy tests and nothing. Where is my period?? Now my other <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> app “modern fertility” says I could be ovulating this week. Can I ovulate twice with no period in between?

If you can help me, please do. Thank you!!
