I'm 40 weeks pregnant and I am now a couple days over due. I don't know if I've lost my mucus plug or not.. but I haven't seen any blood or pink just A lot of discharge lately. Um my hubby and I had sex tonight (not that you want to know) but I'm scared that his penis might of hit the baby's head while deep in me. Can that happen especially if you lost your mucus plug?? And another qustion is.. ur mucus plug will be blood or red tinge right? Cause I don't want his sperm to get to the baby especially if were trying to help with the labour and we don't know if I've dilated. Help please! And third question is.. if I'm already dilated I must of lost the plug right?

You may not ever notice losing the mucus plug... it can have some streaks of red or pink blood in it, but it doesn't have to.
Unless you were doing something unusually creative, hubby won't hurt baby... :) Even if you were dilated a little, baby is still cushioned by the amniotic fluid.
Hope things get going for you soon!
