So AF came a week early and my breast have been a little swollen and very sore for about a week now. Ive also been super nauseous lately. It is very rare that my cycle is out of wack or anything other than cramps bother me, its usually very steady... I took a HPT 2 days ago (right before my period started :/ ) and it was negative. Is there still a chance i could possibly be pregnant? I've been trying to conceive since I lost my baby back in March. TIA
