Discharge and bleeding

Hi, mum of an 8 year old here so long since forgotten how pregnancy was.

I had unprotected sex (I suspect possibly during ovulation, periods are irregular) then had very very light bleeding on and off for 24 hours. Thought it was maybe AF coming early but it didn’t amount to anything and no typical AF symptoms so putting it down to a possible tear from intercourse or something. Yesterday evening (6/7 days after sex) I had a large amount of white discharge on my pants. It was creamy and white not runny. This is not normal for me. None today so far. Anyone had this experience? Thanks and sorry for the long post.
