i had an accident with unprotected sex yesterday and i really need to know if i am pregnant as soon as possible. My endocrinologist put me on birthcontrol meds to regulate my periods. he said i had under developed ovaries. but i stopped taking the medicine about 2 weeks ago and was on a period for about 2 weeks. yesterday was my first day off. so should i go to my doctor to get a blood test? how can i know as soon as possible? is it even possible that i am pregnant?
