Hi, I have taken Primolut Nor as of the 3rd day of my period (1 pill per day), planning to continue taking it for more than 25 days to delay my period. However I had to stop it after 9 pills meaning 9 more days within the cycle as it was causing chest pain and short breath and I read that it could be one the side effects. I actually called my doctor for that and she told me to stop it, I will get my period in a couple of days or so, so I will be done with it. It is 6 days after the last pill and I still did not get my period, I had severe stomach pain meanwhile, some signs that I will get my period, I was even vomiting my food 2 days ago, and still can t eat well and with gastric pain. Please tell me if this is normal or what I should do.
