Vitamins and no ovulation

[butterfly1]

So, I have been tracking ovulation for years with opk and temping.
I ovulate every month usually cd 9 or 10 except this month...
This month I had a really strong positive on opk on cd4!!!! Also temp really dropped.
I tested again on cd5 and strong positive, temp back up, and solid smiley on dig clearblue. My first thought was am I preggers, as I know opk can turn positive if you are and it just seemed way too early for ovulation and I had a very short 2 day period which also seemed weird. did a test and bfn

anyway I have been opk every day since and there are completely negative, and I mean not a hint of a second line, stark white and I am now on cd 13.

I am beginning to think I am not going to ovulate this month

the only thing I have done different was I started taking vitamins 2 months ago
vitamin d3 100ug, coq-10 200mg and folic acid, I have heard vitamin b can delay ovulation but not vit d, anyone had similar? every month feels like a year lost

The only thing I've heard efffecting ovulation this much is maca. Normal vits shouldn't do it.
