Birth Control

Judy
Does anyone have this issue, in Aug 2016 i switch from tri-sprintec to Errine but I noticed with this new birth control I bleed light but twice in a month. Also I get little pimples around my cheek. Is this normal or do I need to switch. Only reason I switch was because with Tri-Sprintec I was getting really bad migraines now with Errine I don't get any migraines just light headaches here and there. Any advise will help thank you.
