Hi, I took about four pregnancy tests weeks ago and they all were positive and my last missed period was around the 3rd July, making me ten weeks pregnant. Friday night I started to have a brown discharge, today upon wiping myself it had turned red so I went to the hospital, when there the doctor examined me and I was only having brown discharge. She then proceeded to carry out an ultra sound which showed an empty sac but she said that it looked like the start of a pregnancy which has left me confused. I then went and bought a clear blue digital test which showed a result of 1-2 weeks pregnant. I then phoned the hospital and the woman that I spoke to said that I could of misscarried and not realised and got pregnant again without realising as I would of though that I was carrying the baby that I potentially lost. Had this happend to anyone else? I am so confused.
