Well you won't be conceiving any time soon, as you have been put on birth control in order to even out your hormones. You should stay on the birth control for at least a few months in order for it to make your cycles more regular and then you can more easily predict when you are ovulating. When are you getting married?
If Loestrin is a birth control pill (and google says it is) you won't get pregnant. You need to stop taking the pill and find alternate ways to balance your hormones. Maca root is great for this, as is vitex. But once you get that BFP stop taking them both!
