YeS, I am 28 weeks pregnant and I've been feeling the same Thg. I asked my doc and he said it normally happen on your second pregnancy . He explained in more detail but too much to type lol .. But I am sure it's nothing to worry about.
I get all sorts of pressure, no I don't remember with it my first it I do with my second and third, maybe it s something to do with having given birth before. If you're worried at all speak to your doctor/midwife. I try not to crouch because it feels uncomfortable. X
