Hi there ~
I understand your concerns and taking oral contraceptive pills
can throw your regular menstrual cycles for a spin and alter them beyond belief in some cases. However, they are also notorious for side effects. I believe that the side effects that you are having is from the loestrin
that you are having. You might want to check for pregnancy
if your due date for the next menstrual period is delayed beyond a week and repeat it in another week if you continue to have no periods. I hope you visit with a gynecologist for alternative ways of contraception
if things do not work. If you are pregnant however, congratulations!
Take care and have a lovely day!
