text: Yes, you could be pregnant.  It will take you longer to find out if you are pregnant than if you weren't on birth control, because sometimes it takes a while for your body to get back on a cycle after you quit birth control, so it is not abnormal to not have a period for six or eight weeks after you go off and that may not necessarily mean you are pregnant.  I would give it three more weeks and then test.  It won't hurt.  But if you get a negative, it doesn't necessarily  mean you are not.  The only way to know for sure is to get a blood or urine test done.  If you got pregnant two weeks ago they would know by now with a blood or urine test.
