Pregnant, PCOS, or crazy?

Kayla
I was diagnosed with PCOS officially earlier this year and have been taking 1500mg metformin for 2 months, but then my doc did research and apparently I had cycts and all that jazz since 2009. Anyways, hubby and I have been TTC since July, and for the last 3 weeks, I've had crazy symptoms that resemble pregnancy symptoms! Nausea, sensitive to smells/ tastes, cravings, sore/ tender breasts, bloated, mood swings, and fatigue. With our first child, we had no clue we were pregnant (was in a low dose of OTC BC pills) because I felt like I had the flu for a month. So I ovulated again this week, and today is day 3 passed ovulation and this evening I've been experiencing cramping. AF is due 9/7, and I have taken a test and it was a BFN. Anyone with PCOS? Advice? Is this a possible pregnancy? Just PCOS screwing with me? Or am I just crazy? Hahaha.
