I just might be losing my mind!

So I decided to try and check my cervix, something I've never done before. And as I find myself middle finger deep while sitting on the toilet I realize I have no clue what I'm doing! What I did feel tho felt completely different from any other time I'd been in there, for other reasons. lol! After is a day late and I ovulated between the 18th and 2pth of August. I seen my Dr today and he said I could have just implanted, so to wait a week and test if af doesn't show up. Then I read online you shouldn't check your cervix during the ttw. I know after I tried checking mine I started cramping a little. Which of course I didn't read that I shouldn't right now until after I checked. Regardless, this waiting sucks. While I'm trying to remain patient .... I'm slowly losing my mind.
