Yes, a high dose of B12 can affect it. I had irregular menstruation symptoms, sometimes half a year and longer without menstruating, and -always- after a high dose of B12 (oral, not injected) the menstruation started a few hours later. This is probably caused by something called intrinsic factor - stomach cells that produce intrinsic factor are destroyed or missing, without them you can't absorb B12, no matter if your diet includes more or less B12. Only very high doses may get through (or injected B12), these high doses are not present in ANY food.
As soon as your B12 storage is emptied (B12 can be stored in the body for 5-12 years or so), symptoms of B12 deficiency occur, it leads to pernicious anaemia,
means that the production of red blood cells is defect, blood cells won't divide any more, you start to have less, but huge red blood cells, since they are not divided. In this environment your menstruation probably stops due to the deficiency of healthy red blood cells.
My conclusion is that a very high dose of B12 probably leads to a sudden rush of blood cells, and this may start the menstruation, even after it has stopped for a very long time. Don't forget to supplement iron, and folic acid together with B12 - since the production of blood cells depends on them. For that reason a high dose of B12 may lead to an iron and folic acid deficiency, if not supplemented, they are all used up to build the new blood cells.
B12 vitamins don't really have any effect on the menstrual cycle - although all round good nutrition does help regulate hormones, so in turn helps regulate menstrual cycles. B12 in particular can help ease menstrual cramps.
Four B12 shots usually will not cause your menstrual cycle to be late. Your cycle can be late if your body is low in vitamin B12. You should talk with your doctor and ask him why your menstrual cycle would be late
