<s>[INST] i am 15 weeks 6 days now, and i had my ultrasound just yesterday, and it says the presentation of the baby is in breech position and posterior placenta grade 0, lowest edge is at the level of internal OS... i havent consulted my ob yet but reading this i am so worried.. what does this mean? is my baby in danger? thanx [/INST] Hi, At this time the breech presentation doesn't matter as the baby is very small. As your placenta is at level of internal or, you have to take some precautions like don't work too much, take bed rest and if any bleeding happens visit your doctor immediately. Placenta in most cases will grow upwards, and it can be confirmed on an ultrasound after one or two months. Hope I have answered your query. Let me know if I can assist you further.  </s>
