Hello... I had a question... My bf and i had sex in february starting week. We had unprotected sex but my partner did not ejaculate. Now i had her periods twice. First in february for 4 days and then in march for 5 long days but it was delayed by 4 days.... But then i had a mild one day bleeding 14 days prior to the delayed periods date so i guess that might have been ovulation bleeding. Recently i have been throwing up a lot like every 3rd day, diarrhea, uneasiness and pretty tired and not in a good shape. Can there be any chance that i got pregnant and am in third month? Can it be pregnancy or is it some other reason altogether?
