Pretty sure I ovulated but...

Megan • Megan💄 Ortho asst🦷 fur mom to two GSDs🐶 3 miscarriages 👼🏼 expecting our first baby Aug 2019🤰🏼
I'm on CD 13 ... Last two days I had positive OPKs and a spike in temp this morning. What kind discharge would have occurred?? I honestly wasn't paying much attention, nor did I think about it!  Also, would I still get a positive OPK if I did ovulate? Should I take another just in case? Thanks ladies!
