Idk what to think

OK so I've been with my SO for almost 3 years strong! I was on the Para Guard for 5 years until November last year and we have been actively ttc since I had it removed... I also downloaded glow the same month and every month my period comes right on time with the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a>... Until this month, and it says I should've started Friday and I still haven't had any signs other than tender breast... I no acne no pm as usual and I really don't know what to do next. Should I test? Is it too early? What yall think
