Not de-pilling before conceiving can be harmful for your fetus..Hormones are very important during pregnancy, they are everything! If you're on BCP your body will probably rely on those progestins/artificial progesterone and estrogens thats why they are so bad for your natural hormone production but thats another story.Then when you get pregnant to short after taking these pills(especially after taking it for a long time) your body might not yet have its natural P production on order and not enough progesterone will cause a misscarriage.
When you are for example using progesterone cream then get pregnant they advice you to use the PC cream until further in the pregnancy(if not until the end) to prevent a possible misscarriage due to a progesterone drop.
