Vitamin D and period? Weird?

Beatrice
So, question - has anyone taken Vitamin D supplements and started seeing changes in their cycle? Like delayed periods? 
I started taking it this month (the full daily allowance) and my period is now about a week late. I have sore boobs and cramping like its about to come but I haven't started yet! 😔 
I've taken 2 pregnancy tests and they were negative. I really don't think I could be pregnant as I've had sex with condoms. 
Any opinion?
