First signs of pregnancy symptoms???

I had unprotected sex everyday from march 3rd-7th about 2-3 times a day when I was visiting my fiance hoping that I will get pregnant and he came inside me every time. Glow says I started ovulating yesterday (march 9th) and I would like to know some of the really EARLY and FIRST pregnancy symptoms that you mommas had or are having. ALSO, I know its way too soon now to tell, but if I possibly do become pregnant, in how many weeks should I take a test?
