hi i have a weird question to ask, i had got my friend a few weeks ago , before that ive had a pinkish discharge , and a milky creamy discharge, so thought maybe i was pregnant ,but i got my friend. and now two weeks after my friend, my breasts are sore,and feel heavy ive had sex but each time he pulls out. ive looked up online and it says stuff like breast cancer or possibly pregnancy , so i was wondering if you could give me a little insight on what could be wrong with me oh and my nipples are tender, not really sore but more sensitive then normal. thanks.
