B6 and trigger shot questions

OK I have 2 different questions...

1.  What is B6 used for? A friend of mine suggested it to me and said it might help with my CM and conception. I bought it but not sure if I should take it - I am also taking a prenatal vit too.

2. Is this bad of me...My last 2 IUI my dr has me giving myself the trigger shot about 9PM the night b4 my IUI BUT once you give yourself the trigger shot O can occur 24-36 hours later (which I figured out that I would maybe O late that night or the next morning). Would it be wrong of me to give myself the trigger shot between 12 - 3 in the afternoon the day before my IUI (my IUI would be next morning 9am)?
I was thinking this would make me O sometime around my IUI.

Twice I have had u/s 32-33 hours after shot and I had not ovulated yet but was just about to.  Both times I had IUI 36 hours after shot and got bfp..  I actually thought ovulation was supposed to occur 24 to 48 hours later.

From my experience, I say time it for as close to 36 hours as you can.  I don't know if  you dr told you differently for a specific reason, but that is what has worked for me.. Good luck to you..

The b6 helps with lengthening your luteal phase. I believe it helps with low progesterone .
