Chest infection causing me to piss myself

Well the title kind of says it all, I have a chest infection and have had it for a week now. As with the usual illness I am bloody fed up with feeling unwell but to take the biscuit, every time I have a coughing fit I'm wetting myself. I had a baby 2 years ago and I'm currently pregnant so I have no chance.

It's gross and I feel really unhygienic and I'm fed up.

Hoping someone on here can understand. How good is tena lady? Is this normal to wet yourself from coughing? Is this just life now?

Sorry for tmi.
