I started my birth control pill pack on April 12, and took my pill at 9
Hi. Thanks for asking in Chat Doctor. You have not mentioned if you have vomited out the sugar pill or the hormonal pill. Efficacy of the OCP depends upon the UN interrupted intake of hormonal pills. No harm can occur if you have vomited the sugar pill but if it was a hormonal pill, then surely the contraceptive protection would be reduced. You need not fear about pregnancy as you have used plan B after the intercourse. But your next menstrual cycle can be delayed because plan B also contains progesterone and a high blood level of progesterone can delay periods. This delay, again can create confusion and doubt about pregnancy. So if your period is delayed, do pregnancy test and rule out pregnancy as that will relieve your anxiety. I hope this is useful to you.
