Hello,
Welcome to ehealthforum
It seems that the delayed periods have been due to oral pill use.Irregular and delayed periods are very common with pill use as it causes changes in the hormonal levels of body.These effects are usually present for initial few months and then subside on their own.Woman also complain of shortened periods while on the pill.
Relax as the periods might start soon.If they do not start even after a week consider visiting a Gynaecologist for evaluation.
Take care!
