I am 19 weeks pregnant and my first baby. This is rather embarrassing to write but I seem to have been leaking a bit or urine throughout the day/night. I had thought it to be discharge so was keeping an eye on it by wearing a pad but I think it's actually urine. Is this normal in pregnancy and if so what should I do about it? I don't want to google it as I will get loads of answers and I'm just looking for some reassurance. Many thanks in advance.
