I went in last Monday (5/22) to find out how far along I am. I know the first time we were "together" was 4/22. Unfortunately I don't have regular cycles so I honestly don't know when my last period was. The tech said I was 6wk1d and was due January 14th. Then two days later I got a call saying there was just a sac and no fetal pull. We have another US scheduled for Wednesday the 31st, but I'm worried. Anyone ever deal with this?
