I think I had it in Tri 1. I got quite a fever and ended up having to have a few cool showers to get my temperature down. I agree, plenty of fluids and paracetamol if you need it. You can have up to 8 tablets in 24 hours (up to2 tablets 4 times a day) whilst pregnant and that will also help with aches and pains and to keep your temperature down (if that's an issue). Hope you feel better soon. If symptoms persist or if you have any comcerns, call your doctor. xxx
