sprintec to regulate cycles?

how long did it take everyone's cycles to regulate on sprintec? *if you had irregular cycles, were overweight, miscarried, etc* me and my SO were trying to get pregnant and had a miscarriage in October. my ObGyn told my it would help to lose weight and I told her I would randomly have spotting in between periods so she put me on Sprintec. since then I've lost 10 pounds, and am finishing my second pack of the BC. so, how long did it take everyone else's cycles to get regular? and when you got regular, when you quit the BC, how long did it take you to get pregnant?? would love to hear from everyone!!!
