Starting third round of provera

Sierra • Young couple ttcing since September 2015! Suffer from pcos and a retroverted uterus. Have also had 3 early miscarriages. I am lucky enough to say I am finally pregnant with baby #1! 💖
I am on cd41 and still getting negatives 😔 guess I'm going to have to start my third round. I just feel like I should wait until my normal actual period comes but it's literally killing me waiting. It's been sense September 2015 when I got my implant out. Still no actual period or pregnancy. I don't know what's wrong with me 😔 provera helped me out the first month but it ended in chemical pregnancy. I was really hoping the second round would do the trick, but I guess not. Very disheartened and am thinking now that of it happens it happens. Been thinking about going on birth control pills to kick start a period. Has anyone done that and it worked?Â
