Period Problems

So I always had irregular periods when I was young and even took BC for about 2 years as a teenager to help.

Now I’m 24, and have been married for 3 years. I took BC the first 2.5 years and as soon as I stopped got pregnant.

Unfortunately, we lost our sweet baby at 9 weeks.

I had a DNC on March 4, and was told I would start within 6-8 weeks. I didn’t, so I took Provera. When it was time to start again nothing happened, so I took Provera again. I just finished the 3rd does of Provera and finished that period about a week and a half ago. I am supposed to go this coming Wednesday to have a progesterone test done. But...I woke up this Thursday (day 11 of my cycle) and had started.

Does anyone have any suggestions or have had this happen before?!?
