Should I tell him?

Kim
So I'm about 5 days Kate on my period and plan on testing in a couple of days, but my question is I had a random hook up with a guy and he used protection but now I'm late. We've had several hook ups over the past 2 years, but this morning I saw him post a picture of a girl he's starting to date. If I turn up pregnant should I tell him and let him have a say in my decision about this baby?
