hi, i know this is really weird,but i can already feel my babys head is engaged about 3cms into my vagina..i have had twins,6 years ago,and heard that the head being engaged early doesnt nessesarily mean anything in subsequent pregnancies- but my twins came at 33 weeks,the layer of skin is very thin around the head,and im getting nervous.should i get checked out? does this mean labour might come early? I have also been getting really uncomfortable braxton hicks since 20 weeks,about 20 times a day,but my midwife said not to worry. please any info would be appreciated! thanks xx
