I get this everytime I'm laying down in bed. The baby likes to push it up high to my ribs cage. It made it so hard that I couldn't move at all or get off bed so when i need to go pee i had to rub the stomach and the baby releases the pressure.
The pain and hardness is gone, I might be dehydrated I had just woke up but I drink almost a full glass of water after I go to the bathroom, just keeping an eye on myself
Does the hardness go away and comes back? If it does it Braxton hicks. The stomach being high yes it's normal. It's the baby and he picks if he wants to be high, low or on the side.
Are you hydrated? I was told I would have more contractions if I was dehydrated. call if you are worried though. Better safe than sorry
