Pill horror stories?!

Recently I started birth control. I've tried to get on it before but I never really kept up with it. This time I got more serious with taking it. I'm about done with the pack. The pill is called tri-sprintec and ever since I started taking the pills, I feel like I've had really bad mood swings... I started my period last Tuesday & my periods are usually 4-5 days, never any longer. But this cycle came around and I've been bleeding for 7 days straight with no sign of stopping... before I started BC I barely ever got cramps but I've been cramping so much with this cycle. I think I'm just gonna abandon birth control all together because my body doesn't seem to enjoy it 😔 Does anyone else have bad experiences with the pill that they are willing to share?
