I had my sibes last season stopped when she was about three days into showing signs of blood,the reason for this was that i was taking her to a show that was a few weeks later. This all happend around start of may 2003 can anyone tell me when she could next come into season as i have been told that she could miss a season for 2004 please help.

It is almost impossible to predict, as anything that done to unbalance the normal pattern can throw timing out the window.  similar things happen to women when they come off the pill, they often don't start cycling normally right off.  Sorry I can't be any more help.
