The outcome of pregnancies in 182 women with threatened miscarriage

The overall rate of miscarriage among women with threatened miscarriage was 14.3%. Older women (31-40) years had a significantly higher rate of miscarriage (27.1%) compared to 18.2% in the 16-20 years age group and 7.1% in the 21-30 years age group. Parity, previous miscarriage, the amount and number of episodes of vaginal bleeding seem to have no influence in the rate of miscarriage. Bleeding in the first Trimester carries a higher rate of miscarriage (15%) than bleeding in the second trimester (5.6%) and bleeding before 6 weeks gestation in particular has the highest rate of miscarriage (29%).
