This is my 3rd baby and I think last night I was having some preterm labor symptoms. My previous pregnancies I have carried to term, so I've never been through anything like this before. Yesterday I noticed an increase in discharge. Wasn't sure if it was my mucus plug or not. Reasoning is because it was clear and only a little throughout the day on my toilet paper. Last night it increased, everytime I used the restroom there was discharge and the color started to change a little from yellowish to pink. I had been having Braxton hicks all day, my belly was really tight. No actual contractions until about 2 am. My lower back started hurting, and I started getting some contractions in my lower stomach. Nothing consistent though, maybe one every 7 minutes that lasted 30-45 seconds. Baby was still moving, and I used my fetal doppler to check heartbeat. So I ended up just laying down on my left side, and fell asleep. I got up to use the restroom in the middle of the night and the discharge had stopped completely. Still had a couple contractions here and there, but I went back to sleep. I think the contractions have stopped now, but I'm still a little sore in my lower back. Im 36 weeks today, so really not ready to have baby yet.
