Alright, I had my ultrasound this morning. I was guessing I was 8 weeks, the OB said I was measuring 6 weeks 1 day and we saw the possible heartbeat. The bad thing is that the yolk sac is large, which can be problematic and may cause a miscarriage. I just went through an miscarriage in October. I am feeling so devastated. Has anyone had this happen and everything ends up working out ok? I really need some encouragement to get through the next week until I get another ultrasound.
