Helpp!!!

Question and someone please answer don't just view it and hit back. I really am confused. I started my dreaded period today and glow says that I ovulated on Wednesday Jan 20th but I didn't ovulate that day and I had sex that day anyways. I think I ovulated on Friday Jan 22nd or Saturday Jan 23rd both of those days I had EWCM. Is it possible to ovulate later than what glow is saying or is this right?
