My uterus had one last "oorah" on T about a week or so after I started, haven't had one since, but my buddy has been on shots for 2 or 3 months and, though he thought his were gone, had one sneak up on him recently. I think it's only considered abnormal after 6 months, so you might just have to give it some more time. Mine were infrequent to begin with, even pre-T, so I suspect that's why they went away so fast.
Regardless, sorry you're still not out of that boat yet, hopefully they'll go away soon.
