Re: US saw only a sac?!
((hugs)) 4 weeks is a long time. I had a U/S at 6 weeks since I was having horrible pain, like can't walk-sit- ect pain, so they had me come in and check for eptopic. Sac/baby was where it was suppose to be and there was just barely anything to see. So if you aren't even 6 weeks yet I could easily see how the dr. wouldn't see anything. Try not to worry yet.
wife and mom-- no other special labels. Just trying to do the best I can.
