Late Ovulation?

Please no rude comments. Be nice to me ladies. According to this app I ovulated on the 19th. However I remember having ovulation symptoms on the 23rd and telling myself (I’m definitely ovulating today) (Cramping, high temp, high sense of smell, nausea, the whole thing) (had intercourse a day after) I’ve had intercourse quite a bit all month… 4 days before AF I experienced intense cramping 3 nights in a row. Everyday I just knew I’d wake up to blood. (Full uterus feeling) (That’s normally how my cycle operates) but instead everyday I woke up it was nothing. I’ve been getting negative after negative test. Blood test was even negative. My cycle normally comes a day or two early. NEVER on it’s expected day. You guys I swear the cramping is super duper mild now. I feel nothing unless I really focus on it. I had a taste of cramps that felt like something stabbing me. It lasted for about 30 seconds and stopped. I’ve been telling my husband that I feel off. I’m so tired and I feel like doing nothing. I’ve had to reschedule two of my clients because all I’ve wanted to do was sleep. And I know that’s not ME. My cm is normally dry right before my cycle. TODAY I experienced both clear cm and milky white. I wiped and seen very light brown discharge. It was not even enough to make me think my cycle was coming. Wish I woulda thought to take a picture. BUT to sum all of this up could I have ovulated late and by a small chance maybe be pregnant..? Even after the negatives? Could it be too early for a blood test to come back positive? AF is due tomorrow.
