Too early to test or just bfn??

Hi ladies! I'm super thrown off this month with my body. Me and my SO did the deed on Oct 7th and my expected peak day was the 8th. I have a strong feeling that ovulation day was correct because I have mittelschmerz (pain during ovulation) that I get Everytime I ovulate! Anyways fast forward to Oct 14th I woke up and when I got out of bed I felt a wetness (sorry TMI) I checked and there was blood in my underwear, I wiped and there was more blood. I was shocked because my period isn't due till the 22nd! Well after that wiping no more red blood, it went to a brown discharge that was super light and now today is gone! I tested this morning and got a bfn! I had implantation bleeding with my 1st baby, but I'm doubting that it was ib since I had the bright red at first. Ugh did i test too early or is it most likely a true negative? Thanks in advance ladies and sorry for the long post!!
