super late

Hey ladies, i’m completely at a loss. So according to ovulation test i ovulated twice this month. I got a positive on the 3rd and then a negative on the 4. Test again a week later with an ovulation test and it was positive again! So i tried a pregnancy test and super negative. I’m almost 9 days late, no spotting, no nothing. not even cramping, but all negative pregnancy test? Is it possible that i could be pregnant just not showing up on pee sticks, or because i may have ovulated twice that it’s delaying my period. I have a doctors appointment on monday to get a pap and hopefully blood drawn to see what’s going on, but i’ve never been this late. Even after I had my son i was always on time give or take a day or two. And i haven’t been stressed or anything, i’m just super confused 🙄😂
