Me and my boyfriend broke up in August. So around that time was the last time we had sex. We always used a condom and I'm also on birth control. Now we're almost 6 months further and I am really scared I am pregnant. I know it's probably very stupid but I just need some reassurance.

For the last two weeks, I've been fedling really sick. I vomited last week, every time I stand up, I feel extremely dizzy for the first five seconds and every night I have really nad stomach aches. My boobs getting bigger and I feel like my stomach is also getting bigger/rounder but maybe that's just in my head (if I am pregnant I would be 6 months far so my stomach should be much bigger). I don't know. I take a birth control pill so I usually skip most of my periods so I can't check with that. The last time I had my period must've been in October but now I read somewhere that some girls keep having their periods during a pregnancy. Can someone help me?...
