So I had gone for the first u/s last week and was told I was 5 weeks along (not the expected 7). I was ok with that but then I got a call from my Dr. office yesterday to make an appointment for another u/s before my next ob visit which is next week. So I called to make the appointment, they scheduled me for this morning....and again they couldn't see anything but the sac but confirmed it's larger than last weeks. They also said my uterus is slightly tilted which makes it hard to see anything and that most likely I will be scheduled for a third u/s soon. WTH??? Shouldn't they be able to see something at this point??
