After having a bit of a whoopsie at school a long time ago...I have been paranoid about "leakages" ever since ...usually I'd wear an ultra thins pad for a week or a few days before I knew it was due "just in case", made a lot easier by being on the pill as I knew exactly when it was going to happen! Now that I'm pregnant, thankfully for the next few months at least I don't have to worry!
