birth control side effects help

Lurix • 🎨Art and the outdoors is all I need 🌲
Hey ladies I'm having some worries. So I just started a birth control called lo loestrin Fe on the first day of my period. I've never taken BC before and I'm usually very regular, having a 4-5 day period. This period lasted 6 days and later I'm having some random spotting that looks pretty fresh. I'm kinda worried. Any similar experiences? 🌸
