Triplets can spontaneously abort one, but can the other two have babies?

My sister always bleeds when she is pregnant with her son. The child was in poor health after birth. You are 4 months old, and the twins are high-risk pregnant women at present. What's more, you are triplets bleeding inexplicably. If you have been bleeding, but the child is still developing normally, you can stick to term and take good care after birth. It would be best if it could stop the bleeding. The baby's mood is very complicated after pregnancy and bleeding, not to mention that you are two babies. Try to stay in bed and go to the toilet at most. Whether it is safe to endure production can only be natural.
