My stomache feels really tight like if its stretching do you know what might be causeing this. If it helps I think I might be pregnant. It feels like when you over eat and you feel really full, but it like this when I havent even ate yet.
your stomach wouldn't be expanding so early in pregnancy... not for a few months. It is most likely just bloating. (I noticed your questions on "trying to get pregnant" -perhaps you aren't pregnant and are getting ready to start your period?)
If you suspect a pregnancy it is wise to get a pregnancy test. As we all know pregnancy symptoms are very similar to the symptoms of many illnesses and ailments and can easily be confused.
