Hello!! :)

I just found out I’m expecting and I’m over the moon (but also very nervous!) I’m 22 (in a week) and am 3w6d today! I was supposed to be starting nursing school in August sooo this is definitely an adjustment. I’ve decided to work full time as long as I can, and start my program in January. As far as all of this, i know nothing!! I have a stepdaughter who will be 3 this year but this is my first. Can anyone give me some tips? I enjoy exercising, is there anything I need to hold off on? Anything I shouldn’t eat? I usually grab a coffee from Starbucks every morning, is this still okay to drink? Book recommendations would be great! I’ve reached out to my OB and my first appt is May 15! Thank you for any advice you’re able to give! ❤️
