Girls, hello. I've had a headache for almost two days now, it's very bad. The pressure was 110 on 40, I drank strong black tea and it normalized. The pressure is back but my head still hurts and nausea started. (I've never had poisoning before and it's too late now, 30 weeks already). I took paracetamol, but the pain doesn't go away much, then again... what should I do?
