I had a chemical in February and got pregnant 2 weeks later. I use ovulation strips and I know I ovulated 3/15-3/16. We BD 3/13-3/16. I should be around 8 weeks. I went for my ultrasound yesterday and was told there were 2 yolk sacs in the gestational sac. These would be identical twins. However, no babies were present, just yolk sacs. The doc keeps telling me I could've gotten pregnant later. We literally only BD the dates I listed earlier. I have convinced myself this is a miscarriage/pregnancy failure. Anyone agree/disagree or have any words of wisdom or similar stories to share? Anything would be appreciated. Thanks.
