2WW routine?

Maria
Hi ladies, might be a silly question but thought about asking anyway? What do you normally do during your 2WW? Do you still have sex with your partners or will this affect the implantation? Can you still exercise? Drink coffee etc? I have been reading lots of articles lately and I find myself changing my routines, because I'm afraid I won't get a BFP if I don't? Thank you :)
