New Birth Control & Crazy Periods

Kristen
I was on Loestrin for about 2 years and stopped because my periods were bad again. My insurance didn't cover the higher dose so I took a year or two off. 
​I started  Sprintec two weeks ago exactly. I spotted on a Sunday and Monday and started bleeding on Tuesday. It's been a week and a day and I'm still bleeding. 
​Before birth control, my periods were 6 days. This one (counting spotting for 2) has lasted 10 days. Is this a normal side effect?
