<s>[INST] I have been on alysena 28 for exactly a month now and I had been spotting for 2 weeks before I started the inactive pills. When I started them I had my normal period but for only 4 day which I usually have it for 8 days. After it stop I had more spotting show up a few days later. Is this normal for the birth control to cause this random on and off spotting? I have also been having unprotected sex so I dont know if that contributes to anything. I was having it before I went on birth control and I never got pregnant so Im not sure if its just the hormonal changes going on due to the birth control [/INST] Hi, If you are young, it is possible to get a few irregular periods. It takes time for periods to become regular. If you are facing some sort of stress at home, this can also cause you to get late periods. Thus, what you can do is wait and see if the pills are causing problems. Also, some females have mid-cycle bleeding. This is known as mittlschmerz reaction. This happens during ovulation. The ovulation then causes you to bleed every 16 days. Thus you will have 24 "periods" per year instead of 12. I hope this helps you. If bleeding is getting severe, then do consult a gynecologist. Chat Doctor.  </s>
