Suggest Remedy For Missed Period

Hi-I just finished my first pack of Loestrin 24. I am now on my 3rd day of the second pack. I used a Sunday start method (after a period starting on Thursday). I had some light bleeding on the 21st day of my pill pack (and the days around that), but have not a period since. I had sex using a condom this past weekend/on my 26th day of my first pack. Should I be worried?
