I missed my pill 2 days in a row. I am on ortho tri cyclen lo and not thinking I took 3 at once. I know I should have taken 2 then 2 the next day. Then I started having vaginal bleeding for nearly two weeks. Now my period is one or two days late. I also had unprotected sex the Saturday and Wednesday before my period was due and tools plan b pills after both nights. Am I possibly pregnant or am I just late?
