Confused af.. idk what's going on

Af is late by over 4 days... supposed to start last tuesday I thought but nothing. Feel like I had 2 peak ovulations... one on the 6th but decided to test last weekend too and got even more positive line last weekend on Saturday . idk if I ovulated late or what but my periods are never late, ever... I want to test but if I did ovulate late then I'd only technically be 7 dpo and I know that's too early. I just dont even know what to do I'm at a huge loss. Havent tested since Thursday and it was negative..
