Oh, yeah, its normal! Bellababy2013 said it well, too! Before I had my baby two weeks ago, I started that pain pretty early, too. By the time I had her, I had to be careful walking. She would move her head & hit a nerve to where I would have to grab something to keep from falling. Didnt feel too pleasent at all.
Stupid phone.. * highly suggest peeing often
Welcome to the wonderful world of kicking babies!! Its awesome to feel them moving but some times you just wish they'd ease up a bit!! I highky suggest peeibf often even when you don't necessarily feel the need cause one good kick to your bladder and you're going to need a toilet asap!!
