I normally have pretty extreme PMS symptoms like constipation, severe cramps, and always craving chocolate. Once in a blue moon I'll get sore boobs for a day or two. I was diagnosed with PCOS over a year ago because I noticed my periods were sparatic. Well this time around, I've noticed some symptoms I don't normally have like extreme heartburn with medicine not helping, sore boobs lasting so far 4 days, really bad nausea, gas and diarrhea, and incredibly tired. (I'm sorry for the TMI.) I'm just wondering if this could be signs of pregnancy or is it just PCOS?

Thanks for any advice.
