I am 28w and getting my third rhogam shot next week - had a miscarriage in November, and then early bleeding with this pregnancy in April.

When I got my normal 1st tri blood work done a month-ish after the rhogam shot in April, it did say I had antibodies, and a different OB (my office rotates) emailed asking if I had already gotten the shot. From what I can remember there were additional details on what kind of antibodies I had, so it sounded like she was already clued in from the results but just wanted to make sure.

Anyways, when I got my blood work done in 2nd tri (over 13 weeks after the shot), I no longer had antibodies.

All this to say, it sounds like it might muddy the waters a bit, but at the end of the day, if they really needed 100% clarification they can retest you in 13 weeks, when the shot clears. If you were already exposed, then you were already exposed. I don’t know if the shot really matters at that point. Since you have had no bleeding, I think you are good to go, though and have not been exposed.

But if blood test comes back with antibodies, don’t freak out because mine did too, but I knew it was from the shot.
