you guys spent the money to get the hair, so like glenn said take some time off. I too am into running, swimming, lifting, etc....I took six weeks off and then slowly got back into it.
Let your scalp heal. Chlorine in the pool early on may not be such a good thing so don't take the chance. I swim now and it has zero negative effects.
Also, your body will thank you for taking the time off (trust me, I am OCD about physical activity too and didn't think I could do it).
