Spotting

Okay Soo I’ve never posted on here before but some advice could be helpful. We are TTC, have been for a while...Almost a year.

So last month when I was supposed to be ovulating I spotted. It was a brownish color. I went to my hormone doctor (been going for a while) and told her about it. She then did a blood test to see if I had a miscarriage or to see if I was pregnant. Came out negative for both. Also I got my period when I was supposed to as well. So now this is the second month and I’m supposed to be ovulating. Well I am spotting again this time it’s a brownish color and sometimes even blood red. No clots or anything... it comes with cramps too. Has anyone ever shared the same experience? Also I did a quantitive B test at my dr office and all came back fine.
