U were right:))..the dr told me exactly what u said. it's the position of the baby that's causing all that pressure on my cervix!
Probably just how the baby is positioned and putting pressure on ur cervix sharp pains could be from baby being on a nerve. But u could always ask ur Dr to check u if ur concerned. I'm 25 weeks 4days and get the same thing I also get a lot of pressure cuz my baby likes to kick right down at my cervix almost feels like she's gonna kick right out of my vagina.
