Last night we DTD and afterwards I will usually always have tightening and some BH for about an hour afterwards but this time they lasted all night. I was able to sleep through them mostly but they started to get a little painful and I had dreams I was going into labor and some even woke me up. I also had a crazy amount of discharge when I got up to use the restroom in the middle of the night. Is this how it's gonna be the further along I get? I'm 31 weeks.
