Im due in 4 days and all last night and today ive been having lower abdomen pains which comes and goes like crampy pains, lower back ache and it takes my breath away when it comes too and does go when i move etc, anyone knows if its contractions or not? Baby has dropped really low as my midwife said hes 2/5th engaged and they couldnt measure his head at last scan due to being too far down...
