Spotting instead of period...anyone else???

Last period at the end of May.

opk showed PEAK on 6/18, so ovulated 6/18, 6/19, or 6/20.

Period was expected 7/3.

*My periods are ALWAYS 7 days long, start out red and end brown with medium flow, heaviest flow on the 3rd day.

Now for the spotting issue:

Spotted light pink twice on 7/6 only while wiping. No spotting or period 7/7 - 7/8. Spotted dark brown twice on 7/9 only while wiping. Spotted brown twice on 7/10 only while wiping. Spotted a little lighter brown once on 7/11 only while wiping. Barely noticed spotted a tiny bit of light brown today 7/12 only while wiping.

Has anyone else had this happen? What was the end result?

Has anyone had a BFP after spotting and missed period? If so, how long after your missed period?
