Am I pregnant ?? Only 18 pls HELPP

Hi guys, I really just need some opinions. I had protected sex two times a a condom beginning of June. I got some rlly heavy bleeding for a couple of days in July and I’m 99.9% that was my period. Now it’s August and I’ve been having some really bad symptoms and idk if it relates to this. For example, I’m always bloated, always burping, headaches, fatigue, and muscle pain
