I had an abortion about 6 months ago. i would like to know what are the side effects of me getting pregnant again. My boyfriend and i had unprotected sex about three weeks ago but he did not cum inside of me. My period has been coming differently since the abortion at different dates. As for now since January my period, comes by the 1st of the month but it is the 7th and i have not recieved my period yet. My stomach feels a little upset but i think its just because im stressing. I dont think im pregnant because when i got pregnant first i knew with a week that i was pregnant.But im not sure. Please give me some advice.
