Birth control period?!?!

So I have been on birth control for about 2 months now and my first period was all dischargey and there was blood and I should start tomorrow or sometime this week due to the white pills

I gave my boyfriend a hand job yesterday and he didn't cum but pre-cum I guess came out and he got it on both of his hands then fingered me

I guess my questions are am I going to get pregnant and why is my periods weird and dischargey
