Brown spotting?

Jess
I had an opk+ (or what I thought was one- was very close) on June 15. Around the 22 I started having left pelvic pain, feeling like a pulled muscle. The 23 was worse. I took a hpt and it was negative. opk was positive! Could this have been when I ovulated?
​I had brown spotting today. Literally one wipe and it was gone. AF due Tuesday. Part of me thinks I ovulated late, because I was pregnant the end of March, and did not get a BFP until 4 days late from AF. Unfortunately ended in an MC so I am unsure if this is going to be a problem for me.
