Brown jelly discharge

Hello!

I am looking for some insight. On Thursday night, I went to put my OvuSense sensor in before bed. When I got up in the middle of the night to pee, it had a brown jelly like strand on it. I thought oh my period is going to start and moved on. (I had mild period like cramping last week as well)

Well.. Here it is Sunday night and still no period, no cramping, no symptoms at all.

Could this have been implantation bleeding? All pregnancy tests have been negative so far. OvuSense stated I ovulated on 7-27.

Thank you!
