I went to planned parenthood today (my insurance doesn't start until next month) they did an ultrasound it was vaginal and they couldn't find anything.. That's where I got my positive urine test too. I'm so scared and was really upset about it. My hpt are still positive and have gotten darker. This is my first pregnancy and I have had 2 mc before. I'm so nervous! Any of you ladies had the same experience and went back for another ultrasound and it was fine?
