Hello, I would be happy to help you with your question.
This is not typical for a birth control pill start. It might be related to irregularity in your cycle that existed before your started the pill. I really cannot tell based on the limited information provided. In your case, I would recommend:
1. Check a pregnancy
2. Continue taking the pill daily
3. Expect that things will regulate over the next 1-2 months
4. If this does not help, then talk to your doctor about a different pill
I hope that this helps and good luck!!
