he's getting deployed

Hey girls so here's the deal, I was seeing this guy for a little bit and we aren't together anymore but I think I may be pregnant with his baby. I have so many symptoms of pregnancy that I'm almost positive I am. Here's the thing , he's getting deployed next week and I'm not sure which day since we haven't talked about it too much. I'm not sure to tell him I may be pregnant or to wait and see if I am or not. HELPPPPPPPP 😩
