I've been on Yasmin for two months I missed day 8 of my first month but got a period that was fine. The second month I had sex on the 28th of feb I was on my pill 9 days at that stage and I was taking it a bit late but never missed one up to that 6 days later I missed day 15(week3) I wasn't happy with my pill so what my doctor said was to finish the pack and instead of having a 7 day gap go straight onto a new pill MICROLITE so two different pills back to back , I experienced break through bleeding in week 3 of MICROLITE just at the end , will I get a period on no tablet taking days ? How will I know if I'm pregnant!
