is it okay to just take bc to get your period back on track?

im on my last pack of bc. she only gave me two months worth but wants me to come back and get more. i don't want to be on it anymore because i feel like it messes with my heart rate and makes me gain weight. (which i do believe it is not a myth) but that's just me. should i be okay without it now?
