Do any of you take antihistamines all year round for allergies? It says online that you can't take the ones I usually take in pregnancy and that the only safe ones to take are the older ones like Piriton. So I take those instead in my 2ww. But it says on the box if you are pregnant ask your doctor. So I was wondering if I should ask the doctor now if I can take them, or wait till I need to go and get a pregnancy confirmed to ask about it. I can get away with taking one instead of 3 a day, but I need one before work, so because they are supposed to be one of the safe ones, should I just wait till I know that I am pregnant to sort it out?
