Ok this. Has been day 3 already but i feel pressure not on my vagina but on the sides like my legs ...i feel like i done a split for the first time n its hard for me to walk .. I feel pressure i cant walk right or get out the bed right ..am kind of worried since with my first he came a month early .. But does this mean the baby head is down there now? Or ... ?? I feel alot of pressure but it doesnt hurt just heavy pressure
