I'm having trouble working out when this baby will be born. Until I had my m/c in January my cycles were exactly 27 days long. My m/c had two lots of bleeds. The first one only lasting a couple of days and then a second lot that lasted a week. My period came exactly 27 days after the start of the last lot of bleeding. Then my last cycle was 29 days. So when I use the pregnancy calculator due I put in a 27 day or 29 day cycle? Obviously it only makes a difference of a couple of days in the due date calculator but I still want to know. Any ideas?
