I have already posted about this but i jsut cant remember feeling anything with my daughter and didnt know i was pregnant for a while with her. i have been having cramps more than i usually do before AF and I should be on CD2 right now....no AF yet. i tested 4 days before expected AF and had BFN but may test again tomorrow..... when would implantation cramps occur? also, do they feel like AF cramps and are they also in your legs? how many days would i get them? I am also still getting a bit of CM which i dont get when i get AF .....help! opinions please! tests are pricey and i dont want to waste one.
