Losing my mucus plug at 32 weeks?

Should I be concerned at all? I went to the hospital yesterday for other reasons and they noticed I was having small contractions (couldn’t feel anything) so the doctor said I wasn’t dilated or thin, but then today I noticed a small amount of mucus, just thought it was discharge or something. Went to the bathroom later on and when I wiped there was more. I plan on calling my doctor tomorrow but I just wanna know if anyone else has been through this at 32 weeks and what happened. When did you end up going into labor after noticing it?
