Positive test and all the feelings

So I have been trying to conceive baby number two for 9 months and just got a positive test!! Yay I’m 35 and my main reason for trying was it’s now or never as I didn’t want a massive age gap, will have 5 1/2 year age gap assuming baby sticks! I’m 2 days before my period is due. Feel sort of overwhelmed right now, I’m excited, scared, nervous and don’t know what to feel. Also feel like I need to do something, any advice on how to help this sink in or what I can do to feel like I’m doing something! I Only tested an hour ago so still very new.
