Update an earlier post!!

So I posted this morning a picture of my spotting at 11 dpo, and asked if it looked like implantation or period. Well I got home this evening and checked again and now there’s nothing. My period is due in a few days but could it be implantation? I usually do not have a period unless I take progesterone and I haven’t taken it this month yet bc I really thought this month was the month I was gonna get my bfp. I’ll attach reference photos.

This morning

Evening

What do you think? Implantation or starting of period??
