I think I’m pregnant

Should I take a pregnancy test if I’m only two days late. Because I have Flo and it says my period isn’t due until Wednesday and I just downloaded the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> and it’s says I’m two days late. Me and my boyfriend have been trying for so long and this would be great news for us if am. I just need help lol
