What should me fundal height be at 21 weeks? They said I was measuring large ( 28 )and should go for the ultrasound. I feel so dissapointed cause I really didn't want to go through the whole ultrasound thing. One midwife thought that my placenta was on the bottom and and the baby has a lot of room being I had twins previously. But still recommended I do the US. I really want a non-medical pregnancy! Also I did the pee test (it turned Green) and have slight protein in my urine, uh. DH can't understand why I'm so upset about it.
