Hi, just after some advice. I have had a cracking headache all day and really could do with taking some paracetamol to try and help me sleep. Am I allowed paracetamol? The other question is I have awful hay fever (which I think is causing headaches too) so can i take anti-histamine! So much advice everywhere but quite a lot contradicts itself. I am 9.5 weeks into my pregnancy. Many thanks in advance
