I remember reading a few posts here about BO with birth control and if I remember correctly, it was perfectly safe. It could just be your body trying to adjust to the hormonal change. When I started my birth control, my body did a weird sort of menstruating schedule for a while before it evened out, so I assume it's the same way. If you're really worried, then UB support or a supportive doctor should be able to answer your questions.
