Hey ladies. So as u may know I experienced light spotting on the 19th for 2 days. Taken HPTs and all came back negative. Now I am 2 days late my AF hasn't turned up, but I am
​Nervous about taking another HPT just yet incase I get another BFN! How long do you think I should leave it before taking another HPT?
