Big belly, dizzy, nausea symptoms. might have a uti or yeast infec. not sure. (-)ive pregnant test. had period 3x after last intercourse. what's going on?

Go see your doctor: These symptoms can be a lot of things and really need to have a health care professional take a look at you.

Please see your Dr: Symptoms suggest prgegnancy, a mass, cyst or tumor. You need an abdominal ultrasound as a minimum. Likely benign at your age. Single urine pregnancy test from pharmacy can give a false negative as can some vaginal bleeding which is not necessarily from a period. U also need to get a urine test if UTI is suspected. Good luck.
