Will I make it?

We're going over to the IL's Sat to celebrate my SIL's bday. Our plan is to wait until after my 1st appointment, which isn't for 2 weeks...I just want to yell out loud "I'M PREGNANT!" I'm kinda nervous about telling my own mom though cause she's a worrier and I'm hoping she just project on me too much. Here's hoping I can hold out!
