Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. According to your description the possibility of pregnancy is less. Because usually during menstrual flow ovulation will not occur and also implantation is difficult. So, if you really had your periods, not any intermenstrual bleeding due to the effect of antifungal drugs, the possibility of pregnancy is less. And you can go for your petogen short as usual, but if you miss your next expected date of withdrawal bleeding, better to check for pregnancy once with Urine Pregnancy Test kit once. I will be happy to answer any further questions. Hope I have answered your query. Let me know if I can assist you further.
