I can start the same day I started the month before (
Apr 21/May 21/June 21) all the way up
to starting the day I ended the previous month...So
Apr 21 was my last, it ended Apr 28 so May 28 is when I could start this month, or any day in between. After I had my son AF started two months later, each month AF would come a week after the day I started the month before...six months after DS was born I got on b/c for two months,. I stopped mid cycle on Mar 29 and got my first AF Apr 21.
