Tmi, discharge in pregnancy.

Hi ladies. I have had increased discharge throughout my pregnancy and from about 6 months ive been wearing panty liners on a daily basis because I find the wet feeling uncomfortable. For around the same sort of time ive noticed that increased activity makes my discharge increase even more. If I walk to the shop or I do anything active then I get a lot more discharge than if I were to say sit and watch TV.. I'm 35w at the moment and it's increased even more again on a general basis but still increased more with activity. Is this normal? If so does anyone know why this happens & if it isn't normal, what could it be? Thank you! 🌻
