Has this happened to anyone else?

So I'm 37 and 5 today and this morning around 5am I started having some pretty intense contractions with a lot of back pain. They started about 10 min apart and by 7:45 they were about 60sec long and 5 min apart so I called my obgyn. They had me come in for a labor check and said I was 2cm dilated and about 70% effaced. She said I was probably in early labor and may pop today or tomorrow. I go home to rest up and BAM, contractions stop completely. I'm pretty bummed. 😔 I lost what I'm pretty sure was my mucous plug yesterday so I thought this was go time for sure. Anyone have this happen to them? How likely is it that it'll start back up again?
