Cramping

I'm 36 weeks and 3 days. I had a ton of contractions on Friday the 28th and then yesterday morning I had quite a few. Some were 10 min apart and lasting for a couple of minutes. This morning, I'm having period like cramping on top of constipation like cramping but I know I'm not constipated because I went yesterday. Which is also something weird that's never happened, I've went poop the last 3 days when my regular cycle is like every 2 days. I also noticed that my discharge is very runny like water almost but with somewhat of a consistancy of an egg white when you first crack an egg. I noticed some globs of mucas plug this morning too. I guess my question is, is labor approaching? I'm supposed to go out of state this weekend (just a few hours away) but I didn't want to take the chance of going into labor there. I have my weekly appointment on Friday before the trip. What are your alls opinions? Thanks!
