Birth Control

Okay so I missed two pills in a row in week 2 of my cycle. Last night I took one, 48 hours since the last one and one this morning at the time I was supposed to. Even before that I wasn't religiously taking it at the same time everyday. Today I realized I hadn't missed 2 but 3 pills this cycle. Should I be scared of pregnancy/ getting pregnant? I'm sexually actively and we don't use any other forms of birth control
