early labor

Last night i was woken by strong period cramps that tighten my stomach and strong in my back. They were on and off for about 3hours. I had to stand in the shower and let the hot water run on my back. I finally was able to relax after and fell asleep. Today after using the restroom i lost my mucus plug I believe. It was two jello like blobs with a tinge of brown blood. Im 38weeks btw. I hope this means labor soon.
