as long as you are taking the pill every day, even if it is not at the same time, it should still prevent
pregnancy, though it may be slightly less effective. to be totally safe, you can use a Condon for extra protection until the end of this pack, big it is probably unnecessary. if you find that this is a common problem, you should talk to your doctor about switching to a long term
method like an IUD that won't require remembering to take a pill every day.
I hope this helps, please let me know if you have any more questions.
