Testing

Sooo here it is February 1st and guess what! I didn't get a cycle for January. 😳 I've been pretty regular maybe a day early or a day late at the most just going by glow. I tested on 1/28 bfn so now I'm afraid to test thinking AF is being mean.. I had what I thought was implantation bleeding 1/16 followed by cramping for a couple days on/off. Is it possible to still be pregnant? I also had a bad face break out around the time I spotted. I should have ovulated 1/11. 😩ttc is so overwhelming.. I took the approach of "JUST LET IT HAPPEN" no tracking etc etc up until I had the brown spotting. So I hope it worked but geesh why did I get a bfn.. Should I test etc any thoughts?? TIA
