27 weeks and in pain 😭

Sy

I am currently 27 weeks with my second son and have been experiencing a very very sharp/ pressured pain in my vaginal region along with sharp cramps in my lower abdomen. I had a check up 2 weeks ago and all my Drs said was if the pain continues to go and buy a stomach support thing that holds your belly up. Most of the pain is in my vagina. If I move the wrong way or spread my legs to far apart it feels as if I just tore a muscle 😣 it gets worse if I move/ walk around to much, to the point where I am bending over in pain and it takes my breath away. There has been an increase in CM the last couple days and today after walking around Walmart for an hour I feel as if I've peed myself. Is this normal? I'm just scared I'm leaking amniotic fluid and my little guy could be in trouble. At my last ultrasound ( 20 week anatomy scan) little man was already head down, if that means anything. Any advise would help. Please and thank you!
