Pregnant?

Britni
I have PCOS and have never been able to detect ovulation on OPK... I had the thin / eggwhite CM during a few days Glow said I was fertile and had intercourse twice. This has now been two weeks ago and AF is due Dec 1. Last week I had headaches, cramps/bloating for about 3 days, on and off and since yesterday my nipples have been so sore. What do you guys think?!
