I have been trying to get pregnant for about 4 months noow.. so Ive been timing my ovulation days... but this month we had done it not during the ovulation days... more like 7 days after the first day of my period. Ive started taking prenatals for about a month... now my breast are sooo sore and they've been for about 3 weeks now... a little after that day? They are noticeably bigger and every time I take my bra off they hurt... or when I wake up.. they hurt. My period is not due until April 8th, but I'm not nauscious... could I be pregnant... or could it be that the prenatal pills are making my breasts sore? Please help:)
