Questioning timing??

So idk how to even write this... I'll start by saying I'm 5weeks and 3 days pregnant (according to LMP). I ovulated 2.5 weeks ago on CD 22. (Cycles are all over so not sure when period was/is due)

I was told you wont start feeling effects of pregnancy until about 5 weeks... but implantation should JUST be occurring?

Since last week I started having a hunch I was pregnant.. we had sex ONCE this cycle so...

But the timing to when things are supposed to be happening seem off...my discharge never dried up and started increasing last week, which was predicted PMS week according to my app.. this last monday I was so dead tired, like exhausted, needing to nap right then and there... and my uterus has been having weird sensations, like gas bubbles but it's not gas and has been happening for week already,just increasing... honestly it feels very similar to earlier baby kicks (YES I KNOW ITS LITeRALLY IMPOSSIBLE AT THIS POINT,.. I'm not an idiot 😂) that's just the best way to explain it I think.

But I should definitely not be feeling so much at this point? My first pregnancy I only felt tired and had the discharge... this time weird sensations.? Is it just the uterus adjusting(or something?) I can't seem to find info about this exactly...
