I was wondering all of the same things actually my af came exactly 4 weeks after mc d&c then So D&C was April 10th, Af was May 10th In June I got my AF June 24, my normal Af date July skipped a month and August it came a little late it came on the 29th. I am guessing I missed a month due to immense stress, Graduation, work etc. Now waiting for Sept. hopefully BFP! We shall see.
