I am 16 weeks with my second, first was a natural vaginal birth, and I'm feeling like my vagina is "bulging" out a lot already. Like its very heavy and even appears to be larger, plus it feels like more pressure in that spot than I remember having with my first. Have other 2nd time moms experienced this? Is it just because my body has already been through this once, and it's just all the extra blood/weight from my uterus?
