Hoping this month is the month.

Hi all!
I was diagnosed with PCOS at age 14. My mom and grandmother have it as well. Both of them had to get on clomid to conceive. 
I'm almost 24 and have been trying for about a year and a half. Nothing is happening. I'm about to get back on metformin and hope that it helps. 
I was scheduled to ovulate the 18th, and period is due in a week. I've been feeling crazy bloated the last couple days and wonder if it could be a sign of pregnancy. 
Unfortunately, although the app says I ovulated the 18th, we all know that our cycles generally aren't regular with PCOS. So I'm not sure what to think.
