So I have very irregular periods, and they usually get even more irregular after I have sex. So I had my last period April 28 and it's been 14 weeks since then and 9 weeks since I last had sex. Now it was protected and the condom seemed fine afterwards. However I have been bloated and have recently gotten sore nipples.  I don't know what's happening. I took a pregnancy test at about 4 weeks after my last time having sex and it came back negative.  Do you think I'm pregnant or is something else going on? My mom got really sick the first time she got pregnant and we're practically twins, so I'm not sure if I am because I haven't felt sick at all. Please respond and help me figure this out!
