well ladies went in this am for my 2nd ultra sound after me going to e.r. last friday. well everything was going realy good had to have it vaginaly then the lady showed me babys heart beat and she turned the screen to herself and then couple min later she was like im pretty sure you are having twins. i started to cry very bad . i have had twin girls identicle dont get me wrong i would be happy but i had them early and they spent 2 months in the nicu and my doctor i had to see was a hour and a half away all the bad memories of my girls came back when the lady said that. i told her please let me know forsure if it is our not. i cannot go thinking there may be 2 i have to know. well then she told me there was only 1 yolk sac she can see and she was not sure if it was twins our the way the baby was laying. that she said she was unsure at that point and was sorry for scaring me like that but to her for a split second it looked like 2 babys one was on top of the other and looked like they where in the same sac. ahhhh i needed to know forsure so she scaned me longer to make sure she only saw 1 baby and in the end she thinks what happend was the way she moved the ultra sound thing it just was picking up the image of the baby on its side then she moved it a little bit and it made it flip flop the picture but the yolk never moved. so she told me in the end of the scan she was very pretty sure its only 1 baby not twins and she told me sorry for telling me that and scaring me. dont get me wrong ladies i would be happy but after my long months with my girls and how hard it was with them i was praying for only 1 baby this time. well its only been a few day since my last ultra sound and the baby looks bigger to me it was realy cool to see it and i got to hear its heart beat threw ultra sound its nice and strong. she thinks im having these cramps and lower back pain cuz im very constipated and gassy she could only do the ultra sound vaginaly cuz im so gassy. but the baby looks very good and healthy. sorry to make this so long ladies i had to tell you about my experiance though . wow i felt so relived when she said just one. she said if it was twins identical or faternal that there would be 2 yolk sacs and she only saw 1` i do have a pic i will post a little later k ladies . thanks or reading this.
