hello i have been taking the progestogen only pill for the past 2 weeks and 4 days, yesterday i had came across with some bleeding, i had checked in the leaflet that came with the pilss to see if it was normal, and it said that it was common and i should carry on taking the pill, but today, it has slightly started to get heavier, and i am worried if this is normal for this to happen? or should i just keep taking it for a few more days and see if it stops it? i really don't know what to do.
