My friend had an unplanned pregnancy and never suspected twins until she went to the first ultrasound and they spotted two straight away. She's coping amazingly with them but her pregnancy was much the same as a singleton, she just got a lot bigger bump.
Well I'm 37 week with twins nd I never suspected it. I don't think there's anything that'll make u think it unless That's just what ur hoping for. Twins run in my family nd it never even crossed my mind that I could be hving them. When I found out i was pregnant i was already 8 weeks nd whn I got my first ultrasound I was about 12 weeks nd they spotted both babies right away but I never thought I actually was.
