I second the existing suggestions to wait until you're fully healed. At 3+ years post-op I'd be comfortable doing this if I really wanted to, but probably not much before - and I'd definitely think twice about the risk of damaging the nerves by piercing the clit directly.
Plus, depending on surgeon and personal anatomy, the clit's ability to get erect may be somewhat different than a cis woman's (that is, larger/more erectile tissue/erectile tissue in unexpected places) and a piercing could compromise blood flow if not expertly placed by someone who actually understands the underlying anatomy and how it may differ.
However, since you're talking about VCH, I think it's all good.

Once fully healed up, that should be safe.
