Period is 5 days late on bc pill, don't take at same time everyday & missed 1 last week. sex 1 week ago. could i be pregnant?

Yes: The period irregularities are almost certainly due to taking pills late and forgetting pills but it is also possible that pregnancy resulted from the same thing. Check a pregnancy test to know and repeat it in 3-5 days if it is negative. You can set an alarm in your phone to help you remember your pills or try a different method of contraception. Hope this is some help.
