Hello girls I'm on the pill and taking birth control pills. I usually take it at 11:30. Yesterday I forgot to take it and that day with my husband we had... I remembered and took it at 00:00. After that I started taking it again at 11:30. Today there is a little bit of bleeding. The period should come at the end of the month. Is there a chance of getting pregnant? I have a history of miscarriage and the baby is only 3 months old so I am afraid.
