HELPPPPPP!!!!!

Hey y’all I’m so confused on what’s going on. So earlier this month I had some brownish discharge when peeing but only enough for it to show on the tissue after I had wiped. Been waiting for my period but have taken multiple pregnancy test to see if I will get an answer. Sadly, I have been getting BFNs & I’m really concerned now. I have 2 children & I am pretty sure I know the signs of if I’m pregnant & Ive been getting a lot of symptoms especially not having a period this cycle. Also to mention, I have a regular cycle. Rarely has it been shy a few days but so far it’s been regular & always on time.

Please If anyone has gone through this before please let me know. My glow app says AF should have arrived on the 24th through the 30th. HELPPPPPPP!!!!!! Please lmk if anyone has had this happen to them too & what was the results or what do you recommend I do?
