Is my cm normal or could I be pregnant

Hey, um well today i was just about to shower and my cm was alot like really really alot and creamy white it was really weird cause this has never happened to me before usually my cm is very very light and last week i had sex with my boyfriend everyday  kinda without any protection 
And i started taking my birth control pills this week 
Soo was wondering is this normal or could i porbable be pregnant and if so how long should i wait until i take a preganacy test?
Thank you everyone for taking time to read my post 🙏🏼
