i had my period around the 23rd of january. I than had a lot of unprotected sex. like the guy i was with gave me the first orgasim during sex, I had some light spotting a couple weeks after my period. Now that it s feb 27th I have not received my period yet. I have been very exhausted and drained. I have been irritable emotional, bloated, slight cramping, a little wet down there but no blood , boobs seem to be bigger, I have experience some nausted, headaches , a little hungrier at times and other times not so much. could i be pregnant? or what s going on
