Hi ladies! My doctor put me on a vitamin d supplement around a month ago while I was on my cycle. I'm now 2 days late and showing negative tests. I read articles online from hundreds of women that were on vitamin d saying that it messed up their cycles and caused them to be late. Has anyone else had this happen to them? If so, did you stop taking them and become regular again? Just trying to avoid going to the dr for an unnecessary visit....
