Went to the ER last night because they were concerned I might have an ectopic pregnancy (it's not thank goodness) and the ultrasound they did said I was 5w5d instead of 6w. And they didn't see a fetal pole. So best case scenario is that I'm earlier in the pregnancy than I thought and another ultrasound will show progression! Worst case is that the baby never actually developed and I may have a miscarriage. :( Now we wait and pray.
