In my TWW

I just had a chemical on October 19th. I knew it could make me ovulate a little earlier or later so I started using OPKs and got flashing smileys for 4 days and then got my solid “peak” reading Monday night. So I’m assuming I ovulated Tuesday. Is there a good chance that my opk was right and I actually ovulated? I had tons of EWCM Sunday night so I’m hoping that was a good sign. I don’t temp so I can’t know for sure.
