I normally take the patch as my way of contraception, but have not had it on for the last 4 months as i have not been sexually active. I am going on holiday to stay with my boyfriend on the 1st of April and will return on the 18th April. my period is due the 6th of April. I do not want to see my period while im away, if i put my patch on next week and keep it on the duration of my holiday will my period still come and will it still be effective.
