Question..

I had a chemical pregnancy back in march. I received a faint positive, then negatives and my period came a few days later on march 21. Well I didn't start my period in April at all so my dr put me on provera and I started on May 7th. We are TTC and I took an ovulation test Tuesday and it was positive. Is that possible to ovulate right after your period? Or is it maybe because my period was started by meds and that was just my normal cycle? Ugh this whole thing can be so confusing..
