First time, what could this be?

So I’m currently be 10-12 dpo, which is probably too soon to test. We baby danced several times during my ovulation time. This is probably completely unrelated, the the last two days I’ve felt so drained and tired, have been having dull cramping, and have been having really lucid dreams and have been having heat flashes in my sleep & night sweats. I just don’t feel like myself. I’m not running a fever. Is anybody else ttc and have/has experienced these symptoms? Could this be a sign of early pregnancy? Or is it to early to be related to that? Would it be worth going to the dr? My period is due on the 11th or 12th.
