Hello and welcome to Healthcare Magic. Thanks for your query.
symptoms which you get before a period may be part of a pre-menstrual syndrome. Now, there are medication which can delay menstrual periods, but they have to be given only under observation and monitoring of a doctor. I'm sorry to inform you that it is not possible to get an online prescription through this website. Moreover, since you are already on multiple medication for your psychiatric problems, you will need a proper evaluation before prescribing any new medication. So, please consult a doctor in your area, preferably a gynaecologist, regarding this matter.
