I'm 27+5 weeks pg and since 1am Iv been having severe cramps really low down and into my nunny. Really sharp painful cramps. Iv rang the midwife this morning and she advised to take paracetamol and ring back later if they don't go. She asked if baby was moving and I said no and her response was "well it's only morning" my baby usual is really active as soon as I wake up. Im really worried and hurts to even stand up. Any advice please?
