Late period but testing negative

[Omc55551]

My period is 8 days late, I’ve taken about 5 tests and they’re all negative, I’m usually really regular but I’m freaking out because I use natural cycles to track my temperature and it’s been rising a lot the last few days which I know is common with early pregnancy - could I be pregnant and still testing negative?? And what else could be causing delayed period/higher basal body temperature?

Hii :)

Why don't you go and get a blood test done to test you hCG levels? That's pretty accurate.

Could you have ovulated way later than usual, which would delay your period?

I think I’m definitely going to go to the doctors at the start of the week just to know for definite! Thank you

I’m wondering if it’s this too, the natural cycles app has marked my temperature rise as ovulation but it’s just so odd as I’m never late 😔 thank you x
