What a day of contractions...

Emily
I'm just about 35 weeks. Had pain lastnight, felt like sharp gas pains but no gas. Could barely sleep. Then this morning I had a super painful bowel movement and all hell broke loose. I was in pain on and off all day that started as just sharp pains that felt like gas or constipation. Came in waves. Then back pressure that was intense and wrapped into my abdominal. That turned painful and I was having hot flashes with them. Took a shower thinking I might be going to the hospital,  and... They stopped! I'm not sure what was causing them, I was chugging water the whole time, but I'm hoping they don't come back. Has anyone had this before? What's your stories?
