I'm abroad and unfortunately managed to get a few mosquito bites before slathering myself in repellent. I'm allergic so they've come up as big red itchy welts, as is usual for me. I would normally take an antihistamine, but the pharmacist has told me that's not safe in pregnancy and sent me away with calamine lotion. The itching is driving me mad - anyone have any other remedies I could try that are safe in pregnancy?? I'm almost 20 weeks. TIA.
