I think I may be pregnant but I'm not sure. When I got my last period it was 18 days late and it was different then most. One it wasn't a full week and second it was heavy the first day and part of the second day and after that it was spotting and before I got my period I took a test and it was negative. Well even during my period I had nausea and I would vomit at least once a day. Well 2 weeks down the road every morning when I take a shower and get out I would vomit but I also had diarrhea but that ended yesterday but not the vomiting. I can't every eat and I'm always tired but can't sleep. Also everyone has been asking me if I'm pregnant even my mother in law, and no I don't look pregnant it's because I can't keep anything down. What do you think?

Have you tried a HPT yet? If not, wait until your next period is due. If it is missing, late, or different than your norm, test using first morning urine.
