TMI Mucus Plug

Julianne • Stay at home mom that cares for everyone`s kids. =)
I am 22 weeks. I was enjoying a late night shower. Went to wash my lady parts, and notice my mucus plug hanging around. This is my second baby, my first was 6 1/2 weeks early. I'm a little concerned that the second will be the same. Any other moms start to lose there mucus plugs around 22 weeks?
