Bleeding after i stopped taking Birth control.

Patient: Hello i was wanting to know what is going on with my body. you see i was on birth control about a month ago but we decided to try to have another baby, i had taken only 4 pills out of the new pack because i was impatient. so i had a period Aug. 25th thru sept. 1st then 4-5 days after i stopped taking the pill i started bleeding again for about 5 days., then it stopped but since yesterday i have been “bleeding” but its been like a brownish red or pinkish color. can you please tell me what might be going on.
