Not sure when to test

Jess
Me and my husband have been TTC for bout 9 months now. I had a miscarriage sept 9th all natural it look me about 6 weeks to get a period and after that I evened out for the most part. But according to glow I was suppose to start my period on Feb 1st. My friends at work convinced me I should test on the 2nd. And it was a BFN . did I test to early or am I just late.
