Hello. The last time i had sex was about 4-5 months ago. Since then, i ve gained some weight, it doesn t look like a baby bump though, but i also broke up with my bf since then &have eaten ALOT. But my period is now only like 3 days long, &i get a really upset, puke feeling at night. Could i be pregnant? Well of course i could be. But is that what you think it is?..
