Hey, I have some advise for you that might actually be good....... GO TO ANOTHER DOCTOR.... PLEASE....My cousin had the same situation and she went and got a blood test and everything that came back negative she actually waited until she missed 3 periods and when she went to the doctor at that time the test came back positive. Just for right now wait but if you can go buy some prenantal pills from your local pharmacy and take those just in case you are you already have a healthy start.
