Our belly's feel so different...how about yours?

everyone is different im 31 weeks me and my SIL are 5 days apart im ahead and her belly is alot bigger and harder then mine so i guess every pregnancy bump is different my sister though is 3 days behind me and she hardly has a bump at all, but i haven't felt hers. i don't know i doubt its anything to worry about mine feels soft in some places one day and hard the next it all depends on where the baby is lying i guess good luck
