If you are 11 weeks pregnant and had a ultrasound and saw nothing on the ultrasound does it mean you are going to miss carry?

The first trimester of a pregnancy lasts up until week 12. If you are 11 weeks pregnant and you have a competent sonographer, there is NO WAY you could miss seeing an intrauterine pregnancy (a normal pregnancy inside the uterus). If you had an ultrasound and the sonographer didn't see anything (even as early as 5 or 6 weeks you should see a gestational sac) then you have probably miscarried already. Take another pregnancy test with your doctor's guidance. Another scenario that might come up (if your pregnancy test is still positive) is that you might have an ectopic pregnancy (where the egg implanted OUTSIDE of the uterus). This is fairly common but can be a serious disorder. The egg can implant anywhere in the pelvis or abdomen, but if you're 11 weeks along and you're not in a lot of pain, then that's probably unlikely. Go back and talk to your doctor.
