Need help. First timer!!!!

Jazmine
So my husband and I are trying for a baby. This is my first time using glow so I'm new to everything on here I followed what it said about my fertile window and all that and I was suppose to start my period Friday the 24. So I'm now 2 days late. When should I test? I don't want to test to early and get a beg and get excited for nothing. Any tips????
