Period 2 weeks late then just spotting?

Has this every happened to anyone? Just looking for a second opinion because I’m not sure what’s going on...sorry it’s long.

So, my cycles have been very regular since I started TTC in July. They’re always 27-28 days and I have started my period the day Glow predicts every time. My last period was October 16 and it only lasted 3 days. Then I had a super weird and long cycle. I tried tracking ovulation but gave up and never got a positive. My period was supposed to come on November 10th but it was 13 days late until I went to the bathroom yesterday (the 23rd) and when I wiped there was a moderate amount of pink-ish blood on the toilet paper. During those 13 days I tested several times and they were all negative.

I assumed I finally started my period yesterday but after wiping that one time, I wasn’t even bleeding enough to get anything on my underwear, didn’t even need to put a tampon in, and only noticed a little bit of brown blood when I wiped last night. I woke up this morning and all day today have not had any blood at all really or brown spotting and it seems like it’s done already.

What the heck could be going on? I’m not even sure if I should log this as a period or just input spotting. When I logged yesterday, Glow set my ovulation date all the way up to November 10th but I don’t know if and when I ovulated for sure. Help!
