7 DPO testing on 2/28 no good signs

Today marks 7 DPO for me. I'm testing this Friday. I haven't had ANY signs this month other than itchy nipples. Is it common to not have any signs so early on? I honestly will be shocked if I get a BFP because I don't feel any different. Last month my boobs were rocks, back cramps, left sided lower cramps. I really thought it was last month that I was pregnant because of all those new symptoms. Then AF came on Feb. 1st. This month though, NOTHING! Just itchy nipples and semi tender breasts.
