To test or not to test

Latasha • Had ectopic pregnancy of march 2010, had 3 miscarriages December 2012-march 2013 with drs help. Now pg w/rainbow baby!
So Glow says I'm due to start on Tuesday but Ovia says Thursday. I am anxious & want to know if I'm pregnant. I really don't feel any different but I have had more headaches. Hoping the HSG helped me get pregnant this time.
