No period after HSG

Erin

I had an HSG done on 6/28 (cycle day 7). I had a normal period before it. There were no blockages. Everything was normal. I used OPKs and I never really got a positive ovulation test. Well. I'm on cycle day 41 and nothing. I had a few days of spotting it was brown and gross. But it was very light (never even had to wear a liner or anything). Negative pregnancy tests still though.

Thoughts? Concerns?
