Vitex or bfp!! Advice please

Started vitex 7/1 i also started AF 7/1 and lasted 7/5 i have very irregular cycles, on 8/22 i had brown blood on my underwear but nothing when i wiped.. a little while later i had pinkish to brown blood. No symptoms of period. I put a pad on just in case and there was only a few spots. The next couple of days i had bright red blood . Then ended 8/25. Over the weekend i had left sides ovary pain very uncomfortable for on and off 30 mins . Me and my husband had sex last night and i bled a little bright red blood then nothing after an hour. Took a test but it was a faint line on a blue dye test and could be an evap. Does this sound like i could be pregnant or maybe vitex messed with my period? Please reapond would love advice!!!
