Lately I have been feeling some weird stuff going on in my lower stomach.. like a flutter or something.. I have not had any other pregnancy signs. I don't get regular periods and this has always been like that. I did have a very light period a few months ago and it was just spotting. The last time i had intercourse was about 4 months ago and we did not use protection, but he did not ejaculate inside of me. Could i still be pregnant?
