Girls the weirdest thing has just happened, the past 2 and a half years I've been on the combined pill, had all my checkups to see if it needs changing and all that anyway I've stayed the same and always had the same pill and taken it everyday. Anyway I had my period 2 weeks ago so I'm still taking my pill and then all of a sudden I've come on my period?! This has never happened before?! I've only ever had my period when I've had my pill break each month and I really don't know what to do my first thought is that I was pregnant and because I've taken my pill I've miss carried? I really don't know x
