maybe baby!!??!??

I'm new to tracking and TTC...last week was my green fertile week. Tuesday to Thursday I tested positive for ovulation, no EWCM. Saturday I definitely had EWCM. we did the BD 5 of 7 days. had some twinges of cramps Wednesday and Thursday. Did the BD yesterday morning. went for a pee 30 minutes after and had what appears to be a decent amount of brown/red blood come out. now if it has been just a rough BD wouldn't it be bright red blood? hubs had already left for work so I text him n he said he didn't notice anything on him when he showered. AF isn't due until November 17th??

then I had this today?

is it perhaps implantation bleeding????

note I never get AF Early
