Pregnant ? While on bc?

Samantha
I started taking combination pill last month, this will be my second month taking it, I had a pregnancy scare but took a test and it was negative. I'm always super paranoid. I am in the second week of my pills for the second month, and I let my boyfriend cum inside of me 4 times during this month all within the last week, do you think I'm okay? Do I ovulate during the second month? Or should I be okay? We are going to use more protection now, he isn't going to cum inside of me anymore, I'm just worried about what we did the past week. Please help! I know it works 99.7% of time, just looking for inputs .
