Guys I'm having this terrible pain in my tummy and sometimes its the pressure that I have to pee but it hurts so bad. There's also a pain in my right side of my back. Please help haven't been able to sleep all night and since I'm FTM it's a little scary. Is this Braxton hicks or round ligament. It's just super painful and I'm getting worried. I'm 21 weeks + 3 days.
