Help! Can you feel yourself dilating??

Savannah

This may be TMI but for a few weeks now, when I go #2 I feel a deep deep pressure in my vagina. (Its not while Im in the process of going #2, its after it already fell into the toilet then I get the rush of pressure after) I read that it may be hemroids in my anus but its DEFINITELY not coming from that area. When I try to explain it, I always say that I imagine that it feels exactly how it would feel if the babys head was right there trying to come out. Its not just uncomfortable but it makes me grab onto my sink and scream in agony like im going into labor. Has anyone else experience this ? Am I feeling myself dialate ?
