Oh sayang, I can understand how worried you must be feeling right now, but it is really a good sign that baby is already moving actively and the heartbeat is strong at 10 weeks, please hold onto that. Many mommies do go through subchorionic hematoma and still have healthy pregnancies, so try not to let the anxiety take over too much, though of course it is easier said than done. Since your doctor has already referred you and KK has opened the pink book, you are in good hands and being monitored properly, which is really the most important thing right now. Do follow up closely with your doctor and let them guide you through this, because every case is a little different and they will know best how to take care of you and your little one. Sending you lots of prayers and positive thoughts, you are doing so well, mama
