PCOS & pregnant?

Courtney
I have PCOS and recently stopped taking my birth control. The last period I had was in May, right after I stopped the pill. Haven't had a period since (which is normal for me if not in the pill). I logged sore beasts for roughly a week on June 18th and have had sore breasts again now for the past week or so. But not like super sore, just the nipple are tender to the touch. I've been stressed at work to the point of tears and slept all day Saturday and most of Sunday. I took the clearblue brand and it immediately showed positive. This would be my first pregnancy if I'm really pregnant. I bought two more tests to take later, but should I be worried about a false positive? I'm afraid to be excited about this. Suggestions?
