question about ovulation!!

Allison • 👼🏼2016❤️ ttc our rainbow baby❣️🌈👶🏼
So I'm pretty new to this, when I miscarried in September we weren't really trying to get pregnant. But AF came on December 31 and didn't leave till the 5 of january. For the past couple days I have been having slight cramping on my left side and my CM is like a watery substance. Is it possible that I could be ovulating? According to the app I don't start till the 16? Please help!
