Confused with ovulation

Ok so this may seem like a stupid question but I know when you get a positive OPK it's means you're going to ovulate within the next 12-24 hours, I know the egg stays alive for 12-24 hours. And it can take up to 10 days for implantation?

So if I'm right does that mean if I got my positive OPK Friday afternoon, I would have ovulated at some point Saturday, during which Saturday and Sunday is the period the sperm and egg have to meet and fertilise and implantation would then occur up to 10 days after?

Meaning the earliest I could get a positive pregnancy test would be next Wednesday

Sorry for just a long question
