So i am 34 weeks pregnant and have been having period like cramps for couple of weeks now. I am not concerned about them because i know it is BH. But as I progress in pregnancy my belly is getting harder like a stone. Is this because of BH?

I am in high risk of preterm labor and doing shots to get baby ready but the doc didnt mention anything about belly being so hard. When i seat i have to open legs because touching it with legs is very uncomfortable and lying in bed is also hard. Anyone else like me? 🙄
