Hi there, I have understood your concern and I will suggest you the best possible treatment options.
As you have stated that there is chance of
pregnancy , as a cause for your delay in the menstrual cycle, you need not worry about pregnancy.
Secondly, there is no effect of
MMR vaccine that will lead to delay in the menstrual cycle. In my opinion, change in your workplace location and time zone can have impact on hormones responsible for menstrual cycle.
You can simply wait for the onset of menses, or you can opt for
progesterone withdrawal. Please seek prescription support from your treating doctor, for 5 to 7 days course of
Regestrone tablets, and get informed about the withdrawal bleeding.
I hope this answer helps you.
Thanks.
