I'd wait hun. I don't have this piercing, I have labret, nostril, lobes, however some basic principles apply to all piercings.
1) It takes a lot of energy for your body to heal a piercing. It should be treated as if it's a minor surgery wound. If I remember right it's 3 months for a Christina. Seeing as your body will be under a lot of stress during training (mental and physical), it would be unwise to mix a piercing with this. Recover fully, then get it done. Stress can slow healing down by as much as 40%.
2) It's very easy to think that it should heal fine but sometimes all it takes is one knock and then the healing can be set back. For this reason, if I knew I had to do something stressful coming up just after a healing period, I would get it done earlier, or wait. I allow an extra two weeks on top of the base healing time for all my piercings also to allow for set backs.
3) If you do get a piercing during a stressful period, then it'll require more aftercare and salt soaks and even this may not prevent problems.
As for time off, I would give it a week and then carefully consider my chances of knocking it on the pole. It may be you have to scale your moves down a bit and do things that are more gentle or less risky for "crotch knocks" as I call them lol. I guess some slide moves could be at risk of knocking it too, or ultra flexy ones involving the leg. It's hard, it's not like I've sat there and thought "well I wonder how this particular area is affected?" lol. I would be wary of clothes pulling on it.
I can't really fully answer how long you should leave poling after getting it done, if at all. If it is possible to pole with it, you may need to consider doing more salt soaks before a session, and a quick rinse after. Sweat and crusties can irritate the wound from being pushed into the piercing though. I know you can get a sea salt spray, maybe that would be useful to carry with you?
