How long after a medical abortion can an external septorhinoplasty be performed?

I have recently discovered I am pregnant and made the decision I cannot continue with the pregnancy, as I am experiencing Posterior nosebleeds most days, of which make me feel terribly poorly. My question is how long after a medical abortion can I receive external septorhinoplasty? This isn’t a decision I have taken lightly, however I must put my health first before something that couldn’t survive outside of my body, I wish my (presumably now ex as he is ignoring me) understood this.
