Some spotting can be normal but it's good that your doctor wants you to come in. I had some spotting with my second pregnancy (at 7 weeks) and it was diagnosed as a threatened miscarriage. My ER doc and ob both told me the same thing, that threatened miscarriages happen in about 50% of all pregnancies and that about 50% of those go on to have normal, full term pregnancies. For the other 50% it's the beginning on a real miscarriage. So spotting is very, very common and most spotting isn't diagnosed as any sort of miscarriage.Oh, and my second pregnancy turned out just fine. The only complication I had was gestational diabetes. In fact, my spotting wasn't as bad as I'd initially thought. It was just a little bit, but it scared me. I went to the ER and by the time I got there the bleeding had stopped. My cervix never even dilated. My ultrasound showed my little baby (a boy) with a strong heartbeat and he was moving a lot. So try not to worry. If you aren't having any pain or cramping chances are good that everything will be fine.
