6dpo symptoms

Ok ladies.. I am looking for some opinions. I am currently 6dpo and my symptoms are exhaustion, gassy, nausea, tender nipples, backache and light cramps. My temperature dipped yesterday to my cover line but went right back up today. Do you think these signs might be a hopeful thing? I'm hoping and praying!!
