If you had an ultrasound and they didnt see a baby or detect a heart beat then no there is so NO way your pregnant!

Thank You So Much, I was freaking out. I still have anxiety about this though, do you have any ideas about how to stop stressing?

Your welcome..Have you gotten a blood pregnancy test..? They are more accurate then the urine.. Did yall use protection when you had sex? As far as the symptoms if a woman thinks she is pregnant the body can play tricks on you and can mimic signs of pregancy.. I really do think if nothing was seen on the sono your fine.. When did you get the sono? That is a VERY IMPORTANT ? Here is some info for you..~~Week 5: Baby's heart begins to beat Your baby at week five (three weeks after conception)
At week five, your baby is 1/17 of an inch long — about the size of the tip of a pen.This week, your baby's heart and circulatory system are taking shape. Your baby's blood vessels will complete a circuit, and his or her heart will begin to beat. Although you won't be able to hear it yet, the motion of your baby's beating heart may be detected with an ultrasound exam.. Hope this helps.. Any ?s just ask..

I got the sonogram last week so if I had sex on April 17th, would it have shown up?

Yeah it should have..

So do you think that the brown/red discharge I experienced after having sex was possibly due to rough sex?

I dont know exactly what its from.. sometimes it happens to me also, either a few days bf i start my period or a few days after it if i have sex..
