period help !!!

Courtney
I moved from Houston to Lubbock Texas ((northen part)). Wondering if this maybe played a partin my period flow being heavier the past two months. I've been on BC for almost 4 years, consistently, and I rarely bleed on my period and never have cramps. Last month (first month here) I was actually bleeding instead of discharge and this week I'm cramping like a MF and have a heavy flow. Plz help me lol
