BFN :(

Regina
We have been trying for over a year now since last MC. For the last 2 weeks I have had pain in pelvic region, backache, sore breasts, headaches. Last period was 5/20/15. Started taking tests for past 2 weeks and each time BFN! Last one I took was on 6/19/15. Is it too early to tell? I even had what looked like implementation bleeding on Friday.
