I mc on 3/2 finally started AF 5/18 now I'm on CD 44 and still no sign of AF. I think I had a false positive on a frer cause every other test has been negative. Please tell me I'm not the only one with messed up cycles after mc & how long does it take to go back to normal? I'm calling the Dr tom just to keep them on board. I'm loosing my mind!!
