Sprintec BC pills

Adriana • CNA 🏨 MOM OF 6 BLESSINGS. THANK GOD FOR MY RAINBOW BABY 🌈

So I started a birth control called Sprintec. Because I had a irregular period last month I was a week late but did not used bc. This month I started bc and once again late period. I tested negative on the pregnancy tests. Anyone had this issue with pill birth control?
