On mon night I had painful BHs for about 3 hours, every 8 mins (they didn't get more painful or regular) and since then my stomach has stayed really hard. Felt fine yesterday. Last night I felt really sick and still do today, plus have the runs. Still feeling movement from baby. Is it just part of preg joy? Not the first time so I should know!
I don't know if it's normal but why not give your midwife a call to put your mind at rest? She'll be able to check you over if necessary.
She may send you to the assessment centre at the hospital to monitor the BHs but don't panic, I got sent there a lot in the last 5 weeks or so and it frightened the hell out of me every time and everything was fine.
