My periods are a 28-day cycle. I was sexually intimate with a man, 15 days after my menstruation. There was no intercourse, but only foreplay, causing a lot of fluid discharge. I have not got my periods yet. Also, by mistake, I took the Regestrone 5 tablet before dinner instead of after. Could that be the reason for the delay? I have attached my urine and blood test reports for your consideration.
