It depends on how you're taking the pill, BeteNoire. On the pill, women don't have real periods. It's called withdrawal bleeding. When the hormone pills are skipped for one week per month a fake period occurs. Back in the 1960s, when the pill first became available, doctors thought women wouldn't feel feminine if they didn't have periods. All pill packs substituted a different colored pill, which was just a sugar pill, for one week per month so the woman took a pill every day. It's during the sugar pill phase that the fake period occurs. Women were not informed they were taking fake pills one week out of every month. Nowadays, some pill packs don't bother with the fake pills.

These days, many women take the pill in such a way that periods are suppressed altogether and they still feel feminine. If you're on the pill, you really don't need to have a period. If you want to have one, it may take several months for your body to adjust to the new hormone levels so you will experience withdrawal bleeding. I think it took me about 4 months. Your doctor is the best person to help you figure all of this out for your own specific medical needs.
