If spotting after starting to take Vines birth control pills is less than 3 months, is this a cause for concern?

To @Альона:

In the first months of using the contraceptive pill, spotting and mid-cycle bleeding may occur. The body needs time to "adapt" to the hormonal changes that occur under the influence of the hormones contained in birth control pills. This is not a cause for concern.

I started taking birth control pills, I have been taking them for two weeks, after the end of menstruation, minor bleeding has been going on for six days. Can you please tell me if this is the norm?

For @Cjdududu: Typically, withdrawal bleeding (occurring after you start taking placebo pills) while taking Vines birth control pills lasts about 5 days. The duration of the first bleeding (menstruation, in which on the 1st day you started taking the tablets) is an individual matter and can last only 2-3 days, as well as extend up to several weeks. Regardless of how long the bleeding lasts, if the pills are used correctly, contraceptive protection remains preserved.

Hello. I take Vines tablets only for the first month, and the bleeding lasted less than 3 months, because only a week. Is this a cause for concern? Could the drug have stopped working? I note that I take the tablets regularly from the first day of menstruation and I have already had intercourse without any other protection than the tablets.
