Sorry might be TMI but need advice

Paola • Mommy of one TTC baby #2
I had a lot of white discharge while having sex with my boyfriend today! I went to the doctor for check up yesterday so I know I have no std or bacteria I thought that I was just extremely wet but it was to the point that it leaked all over the bed!!! Is that normal?? Is it because I'm in my fertile window?? Plz help!!! Thank you!
