When you got a beta done how many hours did it take until you got the call from the doctor!

I just went to my specialists today to do a beta test because I got a positive digital yesterday and I just took another clearblue a few minutes ago and it still says pregnant. I went at 8:30 to get my beta done and its now 12:30 and I am so nervous I wish my phone would ring already. I'm soooo anxious 😬 I already picked up a onesie and have my pregnancy test ready to put together to surprise my husband when he gets home from work. Hopefully they call me before he gets here! How long did it take for you to get your call back?
