i had a subchorionic hematoma that they think may of caused my placenta abruption in 2010 my son was born at 24weeks (640g) i am currently pregnant(11 weeks) and so scared it will happen once again! I have been cramping and having slight bleeding since ive found out ...i had the same with my son and was told its normal its normal! intill i stared to really bleed at 17 weeks and pass clots and thats when they said it was caused from a SCH which at that point my placenta had started to pull away, causing a hole in the sack and i lost all my water ! The doctors then said i would go in to labor and lose the baby and if i did go to term he would never breathe on his own.... well i spent the next 7 weeks laying on my left side and drinking 5 litres of water a day well i did go into labour at 24 weeks and my son spent a total of 134 days in the NICU and today he is very active and happy 18 month old it is not something i want to go threw again as im sure you all are aware of so i think thats why im looking for as much information on SCH and placenta abrutions as i can! has this happened to you ?has it happened twice ? and what did your doctors tell you?what do you think caused it?
