probably but there are soooo many variables to consider such as the dosage of your bcps the type and what you meant by "a few days early". things should straighten out in this next cycle assuming you take them as prescribed.
my period came 4 days early. i have been on birth control for 6 years i'm 22. usually have very regular periods. i took my bc pills early for a few days and my period came 4 days early. any reason why this would happen? did taking the pills earlier induce the period?
