So, i am due october 21st, and decided today that i was going to see if my cervix was opening or not. I went ahead and did the self exam, and felt my babies head.. is it completely normal to be 30 weeks and feel the babies head without necessarily trying?(i didnt need to go too far) .. just nervous because i know there is usually the mucus plug to protect against infections etc.. would i have been able to feel the mucus plug, or is it not there?
