I have been on the birth control pill for a long time now. I got drunk one night and ended up throwing up, fearing that i may have thrown up my pill, i took Plan B the following day, even though I was supposed to get my period and be off the pill that week. What effect will this have on my cycle? will i even get my period? Do i have to restart my pill on a different day or can i just stay with the same day I have always started on? I need help!! Thank you-Shannon
