Not sure

I was diagnosed officially with PCOS when I was 20 years old, just after my husband and I were married. I have been on Clomid, MetFormin, and Progesterone, though I'm not on any of them right now. 
I've had 6 miscarriages, one of which was right after my birthday this year. I'm beyond scared to even think I'm pregnant again because of it. 
We really want kids, but I don't know if either of us can handle another letdown. 
I have a yearly appointment scheduled in 2 weeks with my OBGYN, but I'm wondering if I should try to see her sooner. I'm posting here to vent somewhat, but also to find out if it's just my imagination that I even need to see if I have a BFP or a BFN. Here are my symptoms of the past 3 weeks:
Heartburn
Nausea
Backache 
Headache
Fatigue
Slight abdominal cramping on left side
Gas
Sensitive Breasts
