Late period???

Pamela

So I've always been super irregular with my periods. When I first started having periods I was normal for a few months and then skipped 3-4 months during the summer. Here lately I've been pretty regular maybe a week or two late sometimes and it's never very heavy and only lasts about 4-5 days. I'm currently 34 days late and have been sexually actively but not during my last fertile days. Could there be a possibility of pregnancy?
