Why do I feel so guilty?

I GOT NPREGNANT IN DECEMBER OF "06" AND EVERY SINCE MY 4TH MONTH OF BEING PREGNANT I KEEP THINKING I SLEPT WITH SOMEONE ELSE BESIDES MY BOYFRIEND. EVERYTIME I THINK ABOUT IT NO ONE.. ...I MEAN ABSOLUTELY NO ONE COMES TO MIND. I AM NOW 9MTHS PREGNANT AND...

IT IS STILL COMING TO MY MIND. I MEAN I CAN BE SITTING DOWN EATING DINNER OR JUST RELAXING ALL OF A SUDDEN THE THOUGHT POPS IN MY HEAD. MY BOYFREIND WAS THE ONLY ONE I KNOW FOR A FACT I WAS HAVING UNPROTECTED INTERCOUSRE WITH. I'M JUST WONDERING WHY DOES THIS THOUGHT KEEP POPPING IN MY HEAD LIKE THIS. LIKE I SAID IT HAS BEEN ON MY MIND EVERY SINCE MY 4TH MTH. ANY ADVICE?

Well, maybe you should talk to him about it. If you didn't sleep with anyone else then you've nothing to hide. If your relationship is strong then he will support you and help you in how you feel. Give him a chance. As for why the thought keeps coming, I couldn't say for sure, hormones maybe.

WHY ARE YOU TYPING IN CAPS!?
First, if you haven't slept with anyone else besides him you are fine, there is nothing to worry about. Maybe you should talk to some one about it, it might ease your mind if you let it out. One reason why you could be thinking it was because you truely afraid that you might of slept with some one else and now the baby isn't your boyfriends. It happens a lot of the time, women always have doubts and the what if game when they are pregnant. If you spend a day with a mother who is due any day she will play the what if game. Such as 'what if my baby is born with down's', 'what if my baby is to skinny or what if they have huge medical problems'. a lot of women start thinking about what could go wrong instead of thinking the things that could be wonderful...it just happens. Don't worry to much about it, but if it bothers you so much try talking to some one and getting it off of your chest.
