Trust the negative test or try another brand? One step

[YellowEllis]

I'm currently on CD34 with ovulation confirmed by clear blue digital ovulation kit and temperature on CD19. My temp before ovulation was 36.29, it has risen ever since and today was 36.99. My period was due 4 days ago and hasn't shown up. No symptoms over than excess discharge and sore nipples which I guess could be linked to pms if that's on its way. Natural cycles notified me to take a pregnancy test due to my temperature, I've taken a one step pregnancy test on CD31, 33 and 34 which have all been negative.

I'm guessing 3 negatives at this late stage is enough to trust that I'm not pregnant. I just went to order some first response tests but am I just setting myself up for more disappointment?

Honestly, I probably wouldn’t bother. Naturally on TTC boards, you’ll probably end up with some responses seeking to get your hopes up with tales of ‘oh I only got a positive at 17 dpo!’ or whatnot but in reality that’s extremely unusual.
I’d save your money

Can you attach your chart? Is there a chance you ovulated a little later? If you're temp is still high and there was an obvious shift then I'm not 100% what that means other than you're pregnant. 🤷‍♀️ obviously there's always room for error, but it should be showing up on a test by now.
