Help!

Miranda
So I've been ttc for 9 months now. (I have PCOS)
I know I should have gone to my doctor by now but my work schedules have been so hectic I haven't had the time. My last period was the end of June and I've taken 4 hpts since then but they're all negative. I've been gaining weight despite trying to eat healthy and lose weight, but I have only gained it in my abdominal area. 
I have also not had any pregnancy symptoms besides indigestion I had a couple weeks ago that I had for around 3 weeks straight. I have also constantly felt bloated in my uterus area and the very apparent veins on my breasts.
I have a appointment with my doctor in a couple weeks but this has been kinda driving me crazy. 
Could anyone have any answers to what could be going on with me?
