Should I test or wait??

So I'm not sure if I could be pregnant.. I'm scheduled to start my period on Sunday but I've been having some symptoms or signs of possibly being pregnant. Boobs are tender and feel fuller/bigger. Bra is tighter as well. My nose has been super congested and dry the last 10 or so days. I've been bloated/constipated for about 2 weeks. I've been tired like all day which is odd for me. I've also had acid reflex. And I've had some food aversions. No neausea yet. I took a test last night by it said negative.. What are your thoughts?? I'd love some insight
