Finally!

Ive been putting it off. I dont always do well with changes but I know I need to suck it up and do it. I made changes to my insurance a few weeks ago and today.. I FINALLY made an apt with a new ob. I am really scared and nervous but I just want to know what is going on with my body. Ive had 3 miscarriages at around 12 weeks with my last being in December 2018. Also, the 3 out of 4 cycles my period has been up to 7 days late! Im currently on day 4 of waiting for my period! I was always really regular and I dont know what is going on. Any advice on what I should ask the doctor or what I should bring up?
