I was on the pill for 2 months and then stopped for about 3 weeks and then got on the depo shot. My period was due the same day I got the shot. I still have had no period or bleeding at all. I took a test and it had a white line in the test window. .. so I'm guessing it's negative. But I'm also 13 days late now. Could I have gotten pregnant before I got the depo shot or is it just the depo?
