pregnant ?

Hey girls, 
Im just writing because I'm unsure what to do, I had sex with my boyfriend with a condom of the 14th of December twice but he came twice without pulling it out and using a new condom and once on the 15th of December the next night. My period never comes late anymore and it is now almost 11 days late and I am feeling some of the early signs of pregnancy I found in google. I have not taken a pregnancy test yet. Chances of me being pregnant and what should I do? I am 16 :/
Edit: I am not on any contraceptive but was thinking of getting the pill in January anyway. 
The photo is signs of 2 weeks pregnant and I feel all of them aswell as feeling a little bit constipated. 
~ I am on holiday in Bali at the moment so I am unsure if some of the signs are because of Bali ? ~
