Pregnancy symptoms before implantation?

Em

So I’m only 4 DPO. If I’m pregnant, there’s only a tiny lump of cells sitting in my uterus at this point. It won’t implant for another couple of days. It has been my understanding that until it implants, your body doesn’t really know that it’s pregnant, and that means that it’s pretty much impossible to get symptoms from pregnancy. Despite this, I’ve had to pee like crazy. Way more often than I normally do and with a lot of urgency. It reminds me of when I had a UTI except there’s no pain. I did get a kidney infection a couple weeks ago that went untreated for a while, is it possible that the infection damaged my UT and that’s why I really gotta pee? Has anyone else experienced symptoms before implantation? Curious to see, and feel free to correct me if I’m wrong on anything!
