FTM & paranoid

I've started to experience a lot of pain in pelvis area and have had a lot of lower back pain. I've rang my birthing unit about it and the mid-wife told me its normal as it's the baby's way of getting ready to come and not too stress about it... 

Too me it doesn't feel right.. Anyone else had this problem?? 

UPDATE*** 

I went into hospital this afternoon 2-3 cm dilated & have been given an inducement date!!! This baby is coming!!!
