I'm currently on the pill, and take it such that i only use the active pills for three months, then go through one set of sugar pills after the three months (so that i go through a withdrawal bleed)
im wondering whether my ovulation date would change cos i don't have the withdrawal bleed every month ie. if my last menstrual cycle began on 2nd May, then my ovulation period would have been during 12-16th May. If my next 'period' (or withdrawal bleed) was meant to be for 30th May, but I only kept taking the active pills...would my ovulation period still be for 11th-15th May, or would it have moved forward (or backward) cos I missed the sugar pill week?

Apologies if I've worded it to the point that this is confusing!
