When to test?

So I’ve been off depo for about 6 months now and my boyfriend and I have been ttc for about 3 months. After getting off the depo my period was normal every month. I had one every month lol. My cycle used to be so sporadic that I wouldn’t have a period for a few months. Anyways, so I’ve been pretty regular and I was supposed to start my period according to glow and period tracker yesterday the 03/19, but I haven’t gotten my period, and no signs of her showing up. Since I am two days late and my history of weird periods and just now getting a normal cycle, when do you think I should test?
