Hi, I started marvelon on the first Sunday of my period. My period started on the thurs. It was late by two weeks and behaving differently than usual. My period finally ended on the tues but then started fully again weds morning. And it is still going on. I am travelling in a couple of weeks so I really need to clear this up. I usually only take marvel on two packs back to back to delay my period while travelling. It's the pill I always use and has worked for me...but I don't use it month to month regularly. Could it be that it's stopped working for me.nnalso I'm more nauseus than usual while on it. Should I stop taking the marvel on and try and clear up my system or should I contine and if so then how long will I experience this bleeding? Pls reply asap. Thank you!
