The 7 white tablets in your strip do not contain any hormone and they are not responsible for the heavy bleeding. It is the hormone pills that are the cause. Even though you do not take your non-hormonal
pills to avoid a period, if you start your next month's medication immediately after the previous 21 tablets, then you are protected. Excessive estrogen
levels in the body could sometimes cause symptoms similar to early pregnancy
. Yet, pregnancy should also be excluded. I suggest that you see your gynecologist for an examination and further advice. Take care.
