Just confused. Need someone who isn't related and doesn't know me to just give their opinion haha

So last month glow was wrong on when I started my period but my other two apps were spot on to when I would start. Well of course this month glow is saying I should start tomorrow but everything else is pointing to next week. So according to those apps I am about 6-7 dpo right in the window for possible IB. Started getting some brownish discharge today maybe twice when I wiped and then a little pink maybe twice as well all within maybe 6 hours of each other (yes I peed 4+ times in 6 hours haha and as I'm writing this about peeing I need to go) and now has stopped for the time being.
