Ortho Tri Cyclen was the birth control I was taking.
It can take up to a year for birth control to filter out of your system and it's normal to take up to a year to get pregnant. Doesn't mean that it will take you a year, but it's normal if it does. You cycles may be irregular for the next several months and can make it difficult for you to predict your fertile days. You should invest in ovulation predictor kits which will help you pinpoint your most fertile days and help you conceive.
Good Luck!
What kind of birth control?
