Vitamin absorbtion a sign of pregnancy?

[lisaf]

So I've been taking Vitamin B-100 complex this entire cycle (trying to hold back some spotting at the end of my LP). The excess vitamin comes out in your pee and makes it a bright, neon yellow color. This has been what my pee has looked like every single day since I started taking the vitamin.

Yesterday I didn't have any neon in my pee and was afraid I took 2 multivitamins instead of one of each kind. So today I was extra careful and took on B vit and one multi-vitamin. My pee is not neon today either.

I'm 9dpo, had a longer & lower dip than usual yesterday... could this be a sign?

Only other new sign is that I'm feeling kinda dizzy/lightheaded.
(Ok, everything can be a sign, but does this seem likely?)

Ok, so I wasn't pregnant, but I thought I'd update this if anyone else had information to add or if it helps them.

After my period came, my pee got all neon yellow again. So either I started to implant but my spotting interrupted it (lining deteriorated) or it was something else about that point in my cycle where my body needed more B vitamins. It was very strange though. I'll report back again if it happens this next cycle.
