Taking so long!

So I found out I was prego on Sunday with my HPT. Have taken 2 more since then and still positive. I went to my dr on Tuesday to confirm and they told me I should know by today but could be as late as Monday!! It's a military hospital but they only did a pee test. No bloodwork or anything. So my question is why is it taking so dang long?! It's not like they would test the pee days after right? So they should already know....it's literally a phone call! I'm just very anxious and annoyed that I haven't heard from them yet. Anyone else have to wait this long for dr to confirm?
