Ladies, not really worried but just want to know, is this part of my mucus plug? I felt a small gush but when I looked it wasn't really water but rather a ton of mucus. I'm currently 36wks3d pregnant per my last period, but my IUI date would put me at 37wks exactly. I've had no contractions and as of my appointment last week no dilation or effacement. I had a really busy day yesterday so I'm thinking I simply overdid it. Thanks for your help in advance!
