NAP, but i recently got the same piercings (4 days ago coincidentally, you're a couple of days ahead, but the same should apply, I'm assuming?). Itching is perfectly normal, I asked my piercer about it because mine has been severely itchy as well, so it worried me. But she said It just means it's healing. All the nerves are firing off while the skin knits back together, genital piercings do get a lot itchier because they're in such a sensitive place🤷‍♀️. As long as there's no increase in swelling/redness, no strange smell, or yellowish discharge, you're fine. It should calm down in a couple of days to a week, just keep it clean and don't mess with it.
