Hi there! So I was planning on starting the pill and I did a lot of research etc. talked to my doctor and therefore got the sample packs of Marvelon. I took one pill on the Sunday after my period started.. but then after further research that night I sort of panicked and decided maybe it wasn't a good idea to start.. so I didn't take anymore. I figured one pill wouldn't be enough to screw up my cycle or give me side effects, wrong? Now it's Friday (4 days after I took the one pill) and my period has started?! Was that one pill enough to mess me up and start my period two weeks early? Will it only last a day or two or will it be like a full cycle?

Any insight would be greatly appreciated!!
Thanks!
