Exercise - I would check with doc but I think you''re right for the first 3 months anyway 0- just don't get too hot. You're not supposed to go in spas and hot tubs for that reason.

Diet: These are the things I was told NOT to eat:
Soft serve ice cream - like what you get at MAccas
Large fish - has more mercury in it but tuna and that is fine
No raw meat or fish
no deli meats or salads
no soft cheeses

My ob said I could eat salami and ham anad stuff it was cooked - say on a pizza so you don't miss out too much! Hope this helps!
