Hi, You had suffered from gestational hypertension, which occurs during pregnancy after the twentieth week usually, that had abruption as a complication. In view of the sudden rise in the blood pressure, the placental separation occurred. If the bleeding had been mild, conservative approach would have been taken, by simple observation and interfering only if needed. Perhaps you had severe bleeding that needed intervention. You should preferably wait for an year before you try to conceive again as you had a caesarean section. Also, meanwhile see that your general condition is good and your blood pressure remains normal. Soon after conception, you should get medical attention and take proper care. Good luck.
