gas as a pregnancy symptom?

i’ve been taking the birth control perfectly since august 2018. Recently, I had sex with a condom two days before my “ovulation day” (since ur on the pill u cant ovulate tho supposedly) but after he finished, the condom broke in me. My period is due in 7 days but for a few days before that I’ve been having CRAZY gas like not normal. It sounds silly, but I was just wondering if this could be an early pregnancy symptom? I’m hoping not. I’m not sure if it could be a PMS symptom either. I have been experiencing bloat but it’s not bad. Other than that I don’t really have any symptoms except the basic stuff but it’s not occurring like everyday.
