Odd cycle

Kristen

I usually spot for 1-2 days before and after period, but this month I spotted for 8 days after period (and it was more pink than the usual brown). Now I'm cd20 and have yet to get a peak reading on my clearblue monitor. I'm typically a cd12-cd16 peak. Any ideas wtf is going on? Anyone experience similar? Been ttc 6 months and 4 of those using monitor/bbt which lined up my o perfectly. Going to dr this week for an ultrasound and blood work. My dr told me not to bother with the monitor/temping...but I just can't help myself! Thanks for any help!!
