Dr. Purushottam welcomes you to HCM virtual clinic.
I have gone through your query.
I think I have understood your concern, I will try to suggest you the best possible treatment options.
As per your history it will be wise to get the Rhogam
injection at 28 weeks, as you have history of spotting it is better to get it.
This minimizes the risk of forming antibodies
to Rh +ve cells of baby inside.
As ICT - indirect Coomb's test is negative, you have not yet formed antibodies. Hence it will be advisable to get Rhogam shot if possible. If rules and laws do not permit it then take it after delivery , once baby's blood group
is confirmed to be positive.
I hope my answer helps you.
Wish you good health.
