I just found out yesterday - where do I start?!?!?!?!

This was our 8th cycle TTC so you think I would prepared and know what to do next. I am a little over 4 weeks along & hoping it sticks!! I started taking prenatals - I already had some as my gyno suggested I start taking them throughout the process, but I got lazy (oops).

Do I call my gyno, PCP, an OB?? What should I start / stop doing?

PLEASE - any advice, suggestions, warnings, ANYTHING are much much appreciated!!!!
