Cervical sutures were done for you to prevent miscarriage
due to cervical incompetency in the second trimester of your pregnancy
. and the inj. is also for the safe placement of child inside the
uterus. No harm for the present child. For your future pregnancy the same procedure has to be adopted with or without cervical suture as per the conditions of the cervix
at that time.
Advise. Avoid further pregnancy. Because pregnancy with bicornuate uterus
is a complicated one and if the prgnancy is twins the risk is more both for the mother and child.
