Can oral contraceptives lead to scanty periods over a time period?
Patient: I have been on oral contraceptives for about 12 years - 3 different brands, but similar types - I'm currently on Orsythia.  I have missed my period for the 3rd month in a row, however it's gradually been getting lighter and lighter after switching to Orsythia.  Do you think it's just keeping me from bleeding?  I am very careful and never, ever miss a pill. Doctor: Hello ma'am and welcome.Oral contraceptive pills have a hormonal content and can easily influence the hormone levels and thus, the functions they perform.They can thus easily influence the menstrual cycle (frequency, flow, amoutn, etc.), cause breast tenderness, soreness, etc.So the answrer to your question would be yes, they can.Hope this helps.Best wishes.
