I'm on my first month of yasmin pill and I'm on my 7 days off, this is actually the 7th day now and I've still no period.. I'm supposed to go back to taking it tomorrow for 21 days but then that will stop my period coming, I'm really worrying and don't want to take a pregnancy test as its the most nerve racking thing for a 21 year old who isn't ready for kids! Help!
