Labor?

hi ladies! I am currently today 35 weeks 0 days. Last Thursday (34 weeks 3 days) I met with my OB for some severe pain I was having. Baby was measuring 36 weeks and I was dilated 2 cm and thinned 60%. She said what I was experiencing was labor contractions due to being dilated and she does not want to stop them. She told me to go home, keep an eye on the pain, take it easy, and time my contractions. Saturday morning, I didn’t sleep well. I maybe slept an hour or two of good sleep and when I woke up, I was drenched in sweat. No one else in my house slept hot. It was like I had just showered. I was soaked. I woke up that morning in severe pain. I have a constant “period cramping” pain that never goes away. Saturday morning when I woke up that constant pain I had been having was unbearable. Although I was not having contraction pains I still went to ER to get checked to make sure baby was fine. Saturday, I was still at a 2 but thinned out to 65%. I was hooked up to the monitor and was showing small contractions that did not concern the doctor. I was sent home to take it easy. I rested that whole day. Sunday morning, I woke up feeling amazing. I had so much energy. I cleaned the whole house, organized closets, pantries, clothes, everything. Cleaned everything. I felt great. However, definitely paid for that Sunday night. Last night, I did not sleep. Continued to toss in turn. Had loose bowels twice that night (as in was actually able to use the bathroom) and once this morning when waking up. I’ve been very nauseous feeling and still having those constant cramping sensations. They are in my back and in my pelvic region. Tomorrow I go to have a growth scan done on baby boy. They are going to check his lung development and to check to see if I have dilated anymore. Curious if any other first time moms experienced things like this around 35 weeks. Thank you 😊
