I'm 7 weeks pregnant and for the last couple weeks I've been woken up at 1-2am without fail to what feels like period cramps. There's no bleeding and nothing else untoward and a paracetamol and hot water bottle soothes it to get back to sleep. It's a dull ache more than a sharp pain. Is this normal? I don't like taking paracetamol every day but I don't know how else to stop it to let me sleep.
