I had sex about a month ago [Nov. 7th] and the condom broke. I am not on birth control, so I took Plan B the next day and had my period about a week after that. It was not very heavy and a lot sooner than normal. Then a few weeks ago I started feeling very bloated and differences in my stomach. It is bigger all over and harder at the top. I am over weight soit is a little hard to tell if I am having a 'bump'. I got super freaked out so i took 2 pregnancy test and they were both negative. Since Plan B messed with my cycle I don't really know when I should be having my period again, but I'm assuming it's soon. Can I be pregnant? Are these symptoms of pregnancy, stress, what?
