tmi cervical mucous

Okay tmi.. I have had irregular periods all my life. Got pregnant and had 1 son in 2010 and in 2015 I got pregnant and suffered a miscarriage. At that time I began having periods every few months before the miscarriage. I had another app that I used and tracked my period on that and conceived when it said I was ovulating. Now fast forward to today.. I had my period November 1-6. I used this app and determined my ovulation date (even though I'm irregular). I didn't use any other tests to determine if I was ovulating or not. We Bd through that fertile period. Just 5 min ago me and my boyfriend Bd when he pulled out we noticed a bunch of discharge on him. The bottom of him was stringy looking CM and at the top was a thick white discharge with a little bit of brown mixed in. Does anyone have an idea what it means? Could i just be ovulating now or could it be a sign of pregnancy?
