pregnant?!

Ok guys so this is a really hard subject for me to talk anout but here i go... 
I recently had sex with my boyfriend on June 9th it was a Friday... And well we never really use protection im not on the pill and well he usually just pulls out... And well according to glow I started ovulation on june 11th...
 On Tuesday i began to feel really nauseous and i felt really hungry and had strong craving for food... 
On Wednesday it repeated but i threw up in the afternoon that day...
Ever since then ive been feeling really nauseous lately and been having strong cravings and also ive been peeing more than usual... 
My question is could i be pregnant? 👶🏽 Or is it just me?
