Oh LG. Bit frightening isn't it not knowing what's going on. When did you O? Coz if you O'd late in the cycle, then the pregnancy won't be as far along as you think - if you're going by the LMP.

If your doc isn't concerned about the clomid, then I wouldn't worry. I didn't end up needing clomid, but my OB said that he would do a blood test before each cycle of clomid because he didn't want me taking it if I was already pregnant, so there possibly is risks with it. But I'm sure your OB knows what she's doing

I'm pretty sure there's not much really to see on an u/s until you are about 6-7 weeks pg. We had ours at 8 weeks, and it was just a little jelly bean! But we could hear a heartbeat at that stage.

Hang in there.. hopefully everything is progressing smoothly and you're worrying over nothing
