Chest compressions after breast augmentation.

I have first including cpr training coming up. I've had breast implants under muscle which seem to be healing well at what is now 4 and a half wks. Bit tender and sometimes not sore but a bit of an ache. Like a tight muscle. I'll be 9 wks post op by the time i need to do cpr training. Wil that be enough time? I've postponed once already as i don't think I'd healed enough at 4 wks.
