Confusing discharge/cervical mucus?

I am 10 months postpartum and have had two periods (still breastfeeding) with about a month in between and my last period being about two weeks ago. Tonight, however, after using the restroom I had a big blob of jelly like mucus, clear and lightish purple( or a really faint brown) color and was just jiggly to the touch, but not watery, slimy, sticky or creamy. All I could find when researching was that it could be a miscarriage, but I find this highly unlikely. Hoping maybe someone could offer another explanation. No symptoms of anything aside from maybe slight irritability and not feeling very affectionate towards my husband for the last two weeks or so...anything would be helpful. Thanks!
