Had sex when ovul, used pull out method. 6 days later, took neg test started micronor (norethindrone) that day 1 wk before per, now late. could i be preg?

Possible: This is pretty confusing, but it sounds unlikely you are pregnant. That doesn't mean impossible: pull-out method (bad method) + late period = could be pregnant. Testing 6 d.Po. Is way too early, but you can test 11-12 d.P.O. And get an answer.

Possible pregnancy: Yes you may be pregnant. Repeat a pregnancy test or make an appointment with a physician for a blood pregnancy test.
