I switched my pills to a lower dose. i missed 3 and haven't took my sugar pills. i have been spotting a pinkish red since saturday and now its tuesday?

….: Changing the dose of a birth control pill to a lower dose (usually means lower estrogen) or to a tricyclic pill (often has the work "tri-something" in the name), and especially missing pills cal all be a source of irregular spotting. This will generally self-correct as pills are taken correctly and the body adapts to the new dose. However, if pregnancy is a concern. Take a home pregnancy test.
