Last night as I got out of the bath, I was feeling my breasts to make sure everything seemed normal. But what i noticed were a few little lumps(I am only 18)so it really freaked me out. They are on the inner side of my right breast. I don't know what to think about it. I don't know if it would have something to do with breast cancer or pregnancy. I think it might have something to do with pregnancy but i am not exactly sure. I have been feeling sick during the nights lately but not to the extreme. just heart burn and what not. I have been urinating frequently lately as well i use the washroom about every 1-3 hrs which is more than normal for me. I have been also experiencing back aches as well ( in my lower back) But i am really worried about those lumps so if anyone has some advice that would be appreciated. Oh yea my last period was September 4-9th .....thanks
