Hi dear user, thanks for asking your query.
If your pill is not late by more than 12 hrs then it does not loose its effect.Your history is suggestive of either some breakthrough bleeding( which is commonly seen with lower dose pills containing levonorgesterol) or some local infection. I will advise you to take 2 tablets of microgynon
a day for 2 days to stop breakthrough bleeding.If your chlamydia test comes out to be positive, then you should take azithromycin
1g( both partners).
Hope this helps.
