Ive been late 11 days in my period and I just lost my virginity during my last period, then 3 days after I was "ovulating" and the 3rd the night before my period was supposed to come, we had sex 3 times and all those times we used protection, but I want to know if it could be that I haven't been eating good for the past 3 months I only eat once or twice a day, and I've been stressed out just of the thought of being pregnant, could it be that?
