My boobs are extremely sore (mostly the right breast but the left hurts a bit too) and the past 2 days when i take off my bra at night they feel extremely heavy and uncomfortable. My nipples are ultra sensitive and painful. I have been overly emotional lately but i just made a big move from MA to SC so i think i may be just stressed. My period is so irregular so i have no way to track the or ovulation. I am almost 20 years old and am trying to conceive. i got a neg hpt on friday 02/10/2017 but the boobs just started yesterday. What do you think?
