So I am having some shooting pelvic pain and contractions but haven't seen a mucus plug. my husband asked if I was going to have the baby last night and I said idk. he says well you have already given birth twice. ya three and eleven years ago. idk how he expects me to remember exact details. So how much longer do you think in days? I am due the twentieth.
