For the past year or so, my periods have been lasting anywhere between 10-14 days. This is abnormal for me, as usually they last 6-7 days. I m 32, not on birth control , and am not allowed to take birth contfol. I have been pregnant 8 times, and have had 3 live births, many missed miscarriages at 13 weeks, and one neo natal death. I have also had several d and c s due to the miscarriages (about 12 now), and have also had 2 cerclages placed in he last couple of pregnancies.
