Insight please????

Sooooo my last period was May 8th-13th.

We only had sex on May 17, 18, and 24th and then again on June 5th. Period was due Yesterday june 7th and it didnt come so i tested. Very faint positives.

I tested this morning again and its faint positive, i feel like it even got lighter. However…..idk when i ovulated i wasnt really tracking But EITHER WAY since im 2-3 weeks from the sex we had in may, shouldnt these be darker by now? Because i know these positives couldnt be from the sex we just had on june 5th, because that was 4 days ago.

Pic with 2 tests is from yesterday , other pic with just 1 is today.
