TAMARA and everyone else..when do I STOP taking supplements?

I just got my BFP and I am wondering when do I stop or wean off certain supplements that I was taking. I was taking:
 - Fish OIl
 - Folic acid (which I will not be gettingthrough my prenatal)
- B-complex  (b6, b12)
- Vitamin E

Please let me know which medications I should wean off. Thank you

all this info should be in FAQ, I can't remember it off the top of my head but I know b6 needs to be weaned
