Pregnant? Should I test?

I bled for 2 days, starting July 19, it was very pink but it was only there when I wiped. It completely stopped the day before I was supposed to get my period. I am now on day 2 with no period and it was supposed to start the 21st. The last couple of days I have had flashes of feeling sick when I have felt super hungry I go to eat and the food I usually eat didn’t look good.
