miscarraige is a very broad term and a prelimenary advice would be to have your self checked and evaluated with regards to your basic hormonal
profile and ovulation study along with if possible tubal testing also.
just the complaint that your menstrual cycle has lengthened by 2 days and now it is a 30 day cycle instead of 28 days along with scanty menstruation
could just be a sign of a change in the hormones hence i adviced hormonal evaluation and ovulation study & if you have had an abortion
followed by curettage then ther lies the risk of tubal blockage and hence i suggested tubal testing
a sstandard investigation for any couple having trouble concieving should be a husband semen analysis
