Question about this bleeding I had 2 weeks ago any help would be appreciated

I started to have a lot of brown discharge around September 1st and 2nd I'm sure if it was due to a lot of stress cause I remember I was an then on the 3rd I had bleeding that looked like this only lasted for a few hours I'm irregular so if I don't get my period at all this month I might test i just wanna know did any of you have this type of bleeding before finding out you were pregnant?
