Help me out here!

Faith

Past couple days been feeling sick and the side of my stomach feels sore and has been hurting. Now it could be a number of things and I don’t know what to think and I don’t wanna waste money on a test if it’ll turn out negative. I’m 11 days late on my period but I rlly can’t go off my missed period since my period is always late, which sucks lol. Every time I eat chicken I’m feeling sick to my stomach. Help me ! What should I do?
