Brief Answer: MEDICINES ARE SAFE TO PREVENT MISCARRIAGE. Detailed Answer: Hello, Thanks for writing to us. Ultrasound scan reveals SINGLE LIVE FETUS with SUBCHORIONIC HEMORRHAGE (SCH). It is seen in some percentage of early pregnancies. It is located between chorion & endometrium (on gestational sac). It can cause vaginal bleeding or brown discharge occasionally. However, most patients remain asymptomatic with small or mild hematoma and few are present with threatened miscarriage. Most of them regress naturally. Current statistics shows that chance of pregnancy loss or miscarriage is near about 1-3% with SCH after 12 weeks & mostly associated with large hematoma. Most of them resolve within 20 weeks of gestational age without any further complication. But few percentage has greater risk of development of placental abruption in later months. In such case, urgent medical attention is required. There is NO useful treatment for SCH pregnancies. Wait and watch with serial ultrasound scan and avoiding strenuous activity are the key element in such case. Take adequate BED REST and avoid long journey/ too much bending etc. Here, you can take all prescribed medication by your doctor. It helps to support pregnancy and prevents possible miscarriage. Kindly, proceed follow-up visit to your OBGYN in periodic manner and do next NT scan within given time schedule. FOR BACK PAIN: Apply hot water bag/ bottle or cold ice pack over the back region and start with compression for 20 to 30 min. Correct your sleeping and sitting posture. Muscle relaxant gel like VOLINI etc can be used up to 28 wk. Hope, it helps for your information. Kindly, close the discussion if you don't have any other query.
