Is it too early to test?

Had sex every day during my fertile window, period is now late (not a bad thing) I usually have really bad pms a couple days before period (face breaks out really bad, sore body, cramps) but this time no signs at all. I'm just super tired all the time for no reason, I woke up yesterday and just started crying uncontrollably for no real reason that I could explain, my partner says my body heat is so high it's hard to cuddle at night coz makes us both sweaty which usually was never an issue. Not sure what's wrong with me? Is it too early to take a test? Been about 3days.
