AM I PREGNANT OR BLOATING?

Tanna
No one ever helps me but im gonna see who can actually help.. Do I look more like I am pregnant or bloating? im a 17 year old who has a missed period by 3-4 days. I am having back pains, cravings, and moodiness. im sexually active but I use protection. we always use condoms and he always pulls out before he ejeculates. This past month ive been stressed and had a lot of anxiety because of my new job and relationship issues. I've also been working out a lot on my lower body. Is it normal for a 17 year old to miss her period? Ive missed it before by 2 days.
