Pregnant? Should I test?

Mamaof4 • 4 kids ages 11, 10, 9 and 2 years old.
My period is 4 days late. I tested the day before it was late and got a BFN. I took an ovulation test and got positive peak on Tuesday and Wednesday. Today my boobs are sore, I was slightly dizzy earlier and I got nauseated and threw up a bit ago only to be hungry right after. 
TTC #4 and all this feels like the other  3 but I am afraid to test and get a negative again. Sigh. I got my Mirena IUD out May 12th of this year. Should I test or wait it out a bit more? (According to Glow my next period is due June 12th)
