Please help, My wifes cycles have been irregular during the past few months; I think this has been related to stress at work. She now no longer works and we have noticed that she has had her period as normal in December. She has also been for a ultrasound as the doc thought she may have cysts. There is nothing wrong with her ovaries. This is her cycle pattern: 1st June, 1st July and 1st August. 3rd September then 13th October then, 11th November Now 11th December 2009. Please can you tell me what her ovulation dates would be and what her cycle length would be. We want a second child so bad. I would appreciate any help you can give me.
