Hi, I have a healthy 1 year old son. My last period was 11-15-07. I took 5 pregnancy tests that all came back positive. I went to the Dr today (1/8) and my tests was negative. I have all of the symptoms of being preg, nausea, sore breasts, missed period etc. I have been told that it is possible to have miscarried and still get positive results due to hcg remaining in your system for up to 12 weeks. I am scheduled for an ultrasound tomorrow b/c they think it could be an ectopic preg. I just need some kind of reassurance. Has anyone else experienced something similar? I am so confused, and I really want to have another baby, so you can imagine how awful it was to go in for the first prenatal visit only to find out I am not pregnant. Please help if you know of or you yourself have experienced this. Thank you
