Hormone levels

Okay ladies I need some help! I've never had issues with my hormones being out of wack. Here lately I've been on edge and just real moody. Some days aren't as bad as others. My cycle has been crazy. I've been TTC for about 6 or 7 months now. I've gone to the dr and she said if I wasn't pregnant in 6 months that she wants to check my progesterone level and try me on clomid. I'm about to go insane. I don't know what to do. My attitude has been so bad the past couple of weeks my husband has even said I needed to go to the dr! I'm ready to scream and give up and go back on birth control. At least then everything would be normal! ?
