Weird body? Thoughts and opinions please.. I’m posting here because not everyone in the other groups have pregnancy experience...

With my first daughter back in 2018 I ovulated the 21st and tested the 15th (22DPO) and got a negative and then finally got a positive April 13th with her... over a month DPO, now I only tested bc of morning sickness so idk when the positive would of started to show because it was a solid line April 15th.. not faint at all. I know that my ovulation wasn’t off I did the math and I got pregnant around March 5th. Why was a getting negatives at 22DPO?

I’m trying to conceive right now and I’m 15 DPO no period but still negatives... is it normal for it to take so long to get a positive does my body just take longer to produce the HCG hormone? Thoughts please. I’m currently sore boobs, crampy, sleepy, and get hot flashes idk what to think opinions please!!

I know my first pregnancy isn’t that relevant but it’s to show you guys how long it took to get a positive!

UPDATE. I’m 16dpo now and started what SEEMS like my period! But as you can see I had a period in between my ovulation and positive with my daughter!!
