Hey there. I too have PCOS and i always mistook my symptoms from that as being ones of pregnancy. I can't explain it but the symptoms were just different. I had cramping when i normally wouldnt, my boobs were the first thing i noticed to look different, i had dark blue/purpley veins and my nipples were so sensitive. I was extremely tired from the get go. Nausea didnt set in until about 5 weeks, though i had a bit of a dizzy spell the day i tested. Also my pee was very dark yellow which was another thing i noticed.

And i just knew i was pregnant, i told people i was before i even knew for sure but it was strange i had this overpowering sense of im pregnant.

Goodluck!! i hope you get a BFP!!
