Spotting month after stopping Clomid?

Hey ladies, I was on 50mg of Clomid for 3 months before my OB suddenly moved out of town and I had to find a new OB. I can’t get in to have my first visit with my new OB until mid August and I don’t have any more refills for my Clomid so I’m out this month and next. Super frustrating, but here’s my question:

I got a positive opk one week ago (without Clomid) , but I’ve been spotting brown to pink since then. Enough that I need to wear a panty-liner.

If any of you have experienced this can you let me know? I don’t know if the Clomid messed up my progesterone levels and they’re too low (aka I’d miscarry if I even was able to conceive this month), or if I potentially have something else going on like polyps, cysts, etc.

Thank you!
