Pregnant?! Not sure! Help

Amy
My husband has mostly been noticing my sx. My moods are crazy and emotions are worse, sometimes no appetite at all and other days I'm dying from hunger! And weird cramping and boob tenderness... And this morning he swears my nipples are darker... We are TTC for 4 months now and still have 10 days until my period. Not sure if these sx are way to soon? Although my last period was 3 days one heavy and two light days... Am I being paranoid for wanting to test or should I wait until I miss my period? Please advise!!!
