Help, Looking for some insight!

Natasha

My cycles fluctuate between 29-32 days (I had one weird cycle this year before that was 37 days). I’ve been tracking my ovulation and received a positive cd 14! I’m not 8 days late cd 38 I’ve taken 4 pregnancy tests (different brands) all bfn. Decided to check my LH since my new cycle have started and they’ve been positive for 5 days now... has anyone gone through something similar? What the hell is going on?

TIA ♥️
