Did you ever find out? Im on natazia with the same issue
Hi there,
Your period should come at around/or while you are taking the white tablets. It may be late in few cycles but may happen in a day or so. If you have been taking the pills regularly and on the same time everyday then you should not fear about pregnancy. In case you do not have your periods in the next couple of days seeking the opinion of a gynecologist and taking up urine pregnancy test will be helpful. Do keep us posted.
Take care and all the best!
