Why am i still cramping even tho my period has been over for two days? is pregnancy a possibility or is it something else?

Something else: While pregnancy is always a remote possibility only 2 days after completion of your menstrual cycle, it's likely something else. It could be endometriosis, adenomyosis, it could be a polyp or fibroid (though at your age that would be less likely). I would see a gynecologist. If the pain is severe, they may order an ultrasound to look at the inside of the uterus. Good luck!
