7dpo and dying!!!

Guys I’m being super obsessive!!! Ttc for my third.

Last period was Sept 22. Before that, august 20, before that July 15, so my cycles are a little funky.

Was going off of an app and should have ovulated early Oct but still getting negatives.

Randomly got a positive opk on the 15th and BD the 16th.

IF I ovulated on the 16th I would be 7DPO and am getting negatives. I KNoW it’s early but I’ll prob test every day lol.

Today I’ve had twinges in my ovaries and some Lowe back cramping so worried that AF will come.

Any thoughts about this craziness??
