Hi Ive been taking mercilon contraceptive pill for about two years now, I have two children already, i havent had a withdrawal bleed for two months I had a sickness bug in february but continued with the pills , I finished the packet on friday and still no withdrawal bleed again, what could be wrong, im very worried as I dont want to be pregnant but scared its something more serious. (pregnancy test back in march was negative), im getting cramping like my period is coming but nothing
