I have a very regular period, as in it always comes the day my app says. I can probably count on one hand in 12 years it hasn’t lol. I’m 4 days late and I took 2 pregnancy tests yesterday both were negative (a test with two lines and a digital yes or no test)

Is that too early to test? We are TTC and i have this feeling like at any second my period could start (kind of like a heaviness in my uterus) but it doesn’t, and I’m not cramping like I normally do before my period starts.
