I recently found out I am pregnant, about 5 weeks. I started spotting and went in to see the OB. I was given an ultrasound and they saw a sac but no baby. The OB told me this is most likely do to it being early in the pregnancy. They also did labs and my HCG only increased by 1900 in 5 days and my progesterone is 9.3. I was put on prometrium 200 mg at night supposotories. I am so worried that I am going to miscarry. Has anyone gone through this and if so please tell me about it. Thanks!
