6dpo Spotting

I’m currently 6dpo and I had cramps this morning as if af was going to show her ugly face. I was kind of expecting it being I am on cd54. I got my positive opk on cd 47 and now this morning while I was out shopping I stopped at the bathroom and wiped and saw brownish colored tint on the tp. I was cramping for a little bit and while I was shopping my back started to hurt and I felt like I needed to hold the shopping cart for support if I was going to keep going but then stopped as I got to the car and sat down. I’ve also been getting dizzy spells on the day of my +opk I got a really bad one where I seriously thought I was going to fall over. After that it’s just been here and there but I did get another today.

Got my period October 30th ended 5 days later cycle was 42 days long and got peak opk on cd 29 then I got my period December 11th. Didn’t get my peak for January until cd47 and now here we are cd54. Yes I have taken multiple hpts and all are negative so I don’t know what the heck is going on. I just want AF to show or a positive soon!
