My husband and I have recently decided to have a baby, but I have NEVER had regular periods. I did have a misscarriage in August 2008 and since then my menstual cycles have gone from 59 days to 40 then 30 and my most recent cycle was 38 days... I havent noticed any obvious signs of ovulation (such as the clear slimy discharge), but I cannot afford to buy enough ovulation tests for a whole month... what can I do?
