U probably lost ur mucous plug.. but doesn't mean that ur going into labour. It can regrow. Unless u r having contractions n 5 min apart I wouldn't go to the hospital. . Ur just gonna waste ur time n they r going to send u home. Unless u don't mind waiting there for so long.
Yea it's ok it can grow back.
Could be your mucous plug you can lose it and it can grow back but if you feel worried I would call the doctor
