Hello, on holiday in France I was stung by a mystery insect - never saw it. And my foot swelled up to be enormous with unbearable itching. Someone gave me some antihistamine cream and since I was away I couldn't check with my GP or midwife, so used it for three days. Now I'm back I've read you're not supposed to use these creams when pregnant. I know it's too late, but am worried - has this happened to anyone else?
