okkkk idk?

sooo i've been on BC for over a year now, and i'm normally regular. i had sex right after i finished my period, and that was a week ago. i'm having pain in my lower left abdomen. it could possibly be ovulation cramps, but because i'm on BC i don't ovulate? i always use a condom too on top of birth control. could i be pregnant or are they just cramps? it could also be from stress but idk. please help :/
