What would you do?

So my last period began May 13th and it was very light lasted about 2 maybe 3 days. Btw my periods since april had lasted 5 to 6 days and would come back every two weeks. Anyways About a week later I started getting really tired couldn't hardly keep my eyes open became very nauseous started having an excess of cervical mucus candida creamy consistency and now my boobs are so sore. I took a pregnancy test a little over a week ago and I hate positive but it was a blue dye test, and I don't really trust them. so I took a pink dye test two days later and nothing showed up. should I go to the doctor and get a blood test or just keep waiting and see if it ever pops up on a urine test? I don't know what to do.
