I'm slightly worried, I'm only 5 weeks pregnant and have gone to my Taekwondo class, spoke to my instructor and he said it's fine and to just stop when I feel the need to. Nothing too strenuous but an hour of the way in I felt like I was leaking. I went to the toilet and it seems there's a watery discharge there. I've had cramps today but nothing unusual, nothing while I've been exercising and no bleeding at all. Can someone put my mind to rest please:(
