it is not unusual for someone who has been on the pull for a long time to miss a period. since you have been consistently on the pill you don't need I worry about pregnancy
. also, today's home pregnancy tests
work even on any urine, not just the first morning one. so you can alleviate your worry by using the yet any time of day. you can safely continue the pills just as you have been using them, even if the periods don't come when they are supposed to. I hope this answers your questions, please let me know if you need any more help.
