hi i had a miscarriage at 15weeks this week .The baby was fully formed but the upper part of the head was like soft with water or some fluid inside it was not hard as usual. i did not bleed nor had any discharge.The pelvic scan showed subtle chronic or chorionic hemorrhage.what could be the cause?I am 35 years,58kgs,medically fit,have 2 daughers and have never had any problem with them.
