hidden twin on ultrasound exam

[angels*3]

I have had an ultrasound three times now (12wks, 15wks, and 19wks)  The first one was to check for a twin pregnancy, which they only saw one, and with the other two the tech never looked for a twin at all eventhough I hinted towards them into looking. I have measured atleast a month ahead since I was 12 wks and I have felt movement since 12wks (which made the dr check for twins) I felt that the dr was rather quick as he was way behind with his patients.  I had an emply bladder (I thought that you were not supposed to for an u/s)I also had morning sickness a couple of times and didn't have any with my first two pregnancies, I have been in maternity clothes since 8wks, I have gained 30lbs,had really bad headaches and have been dreaming of twins even before the dr thought it was twins, twins run on my side of the family as well. I also am hungry every two hrs, have to use the bathroom atleast once and hour.  I am now 24wks 5 days and I feel like I am having twins (I have always thought this) I can feel the baby move under my ribs on the right side and down in my pelvic area on both sides at the same time.  What I want to know, is it possible that the first doctor missed the twin and the other two techs didn't see one as they thought that there was no need to look for one?  Could I have a second baby hiding in there and it not have been seen?  I see my OBGYN in two weeks and I feel silly bringing this up to her if there is no way that this could be possible.  Any input on this would be great.  Sorry to make this so long.  Thanks.

Sorry to agree with the others, but I felt my baby move also in the 12th week, and he was by himself at that point.  Don't feel stupid bringing it up with the doctor, though.  If you want to have him tell you for sure, you want to have him tell you for sure.  There is nothing wrong with that.

I agree with pertykitty...it may be possible, but unlikely that after 3 u/s and they still do not see another baby.  Every pregnancy is different...and some women experience symptoms differently with each pregnancy.  8 weeks seems a little early to be wearing maternity clothes, but not unheard of...i think my sister was only 10 weeks or so and she was wearing maternity clothes.  anyway, good luck and here's to hoping you continue to have a healthy pregnancy!

i really dont think there would be a twin unnoticed with those 3 u/s.  i suppose nothing is impossible, but if you are going to your dr regularly, by almost 25 weeks wouldnt your dr suspect? what does he say about you being a month ahead in growth? i am hungry every 2 hours, i pee all the time too, but i only have one little one in there. i know when we feel so big we SWEAR there must be more!  who knows though. let us know after your next dr appt, maybe they can use the doppler to try to find more heartbeats!
