I am 20 weeks pregnant, and this is my first child. I have had a perfect pregnancy until today. I'm having these awful cramps/tightening in the middle of my stomach and around my pelvic bone. I tried using the restroom (peeing) but it was like I was numb or didn't have control. Also, my pulse has been up around 115. I took my blood pressure as well, and it was 140/85.
