Yes normal, I had it done last pregnancy and went into Labour less then 24 hrs later.
It's hard to say start timing them if they're consistent & lasting 60 of more seconds every 5 minutes it's time to go in :)
I started getting contractions right after I walked a lot so how long do you think?
It's your mucus plug labour could be on it's way! I had a sweep on Friday and nothing happened so your lucky :)
It's normal to have blood after as long as it's not a lot!
