advice. help. anything

D
So I'm new to this app.. really only downloaded it to track my period. Didn't pay much attention, and have been using birth control. AF was due on the 12/25 and was late.. still late today. Tonight I decided to test as I had that sick gut feeling and I got a BFP.. well I'm assuming even though one line is darker than the other. Now I'm stuck, me and my partner weren't trying, I'm still very young and don't know what I'm doing with myself yet and want to travel the world before I settle down. I'm so scared and worried, my partner still doesn't know and I don't know how to break it to him😭 I seriously need some advice from some ladies who may be going through or have been through as I am at a dead end. 
Excuse my messy nails .. baldy needing a manicure.  But it is a positive eh?
