(TMI) Does anyone else get pimple like bumps near the entrance to your vag? I've gotten a few of them through my pregnancy and they are really uncomfortable until they go away... Also idk of its from it bleeding a little but I've been wearing pads the past couple days just because of a little extra discharge and after a while what shows up on the pad is yellowish tinged with brown, what would cause that other than the annoying pimples?
