I don't think the two are related. Are you on any fertility treatments? Any family history of multiples? Those will both up your chances. To the best of my knowledge, a history of birth control doesn't affect multiples rates. The chances without family history or fertility treatments are pretty low, but it does happen spontaneously every so often. I'd have to Goggle an exact percentage.
