I'm with these guys! I think 4dpo might be a bit early for symptoms such as tender breasts, but the fact that af hasn't shown up is a good sign so I would test anyway - what have you got to lose??! I know it's daunting deciding to test - i got a bfp 6 days ago and also 3 days ago but before doing the first test i was really nervous cos i didn't know how i'd handle it if it was a bfn :-( but luckily it wasn't and now my breasts are tender most days (well actually mainly the nipples...) so it's possible that you o'd earlier than you thought...? did you do an opk?

let us know what happens - got everything crossed for a bfp for you!
