My cycles are all over the place... My fiancé is getting cold feet and I'm about to just be done.

Cassie • I am 1 in 10- PCOS fighter.
I have PCOS. We've been having unprotected sex since June 2014 not really trying but not trying not to get pregnant. In March we decided to really start trying. I went to my obgyn. She told me to lose 20 pounds (I weighted 221) and come back in 3 months and she'll prescribe me clomid. I ate healthy, exercised, etc. Went back on July 11th and weighed 230. She flipped out and said there's no way she'll prescribe me clomid until I'm 220 again. I don't understand why she wouldn't just give it to me in the first place...I feel like she's playing games with my head. I had an appointment with my primary doctor a few days later and weighed 226. I don't know what's going on. My obgyn put me back on the pill and spironolactone for 3 months and told me to try to get back down to 220. I started the pill on July 12th. On July 27th, I started a very heavy period with horrible cramps. I took the pill religiously at the same time every day and never missed one, so I don't know why I even got a period. Today, my period is supposed to be starting, and it's coming to an end. I don't know what to think or do. My fiancé avoids talking about having a baby completely anymore and I hate it. A lot of the times when we have sex he doesn't even finish in me, which just leaves me feeling incomplete and inadequate. I'm so upset with my body and my fiancé and my doctor and I'm just ready to give up. I see so many of my friends getting pregnant and having kids all the time and it breaks my heart to know I can't do that.
