I am 10 weeks and a day pregnant. I have a terrible headache and I am very hot and clammy. I have had a few sharp pains today in my lower mid abdomen which have only literally lasted a second - nurse said this is nothing to worry about, just things stretching. Is it usual to get hot? What can I take for my headache? I have just phoned NHS direct to get advice, but you girls on this forum are just as good and are actually going through the same worry!
