So my LP seems to be all over the place, but def. on the short side. I picked up 100mg of B6 at Target today. When do I start taking it? After I O or right away? I am on CD10 waiting for O.
I am not expert, but I think you need to be taking it all the time. It can take months to have any effect, and can have no effect for some people, so I don't believe it would be helpful to start and stop it. It's not like progesterone in that AF may not come until you stop taking it.
Personally, I took 50mg for one cycle and it did nothing. I upped it to 100mg plus a B complex for the next cycle. I can't really tell if it had an impact, but I did get pregnant and had an early miscarriage. This last cycle, I continued with the 100mg plus B complex and my LP was 10 days. That's two days longer than any other LP I have tracked. So I am continuing with that combination this cycle, plus adding progesterone after O.
