Hello, i had an accident with my boyfriend 17.8 (but he said that he didnt ejaculate into me), i took an Escapelle after 3 hours from intercourse. Its 7th day and i have like all the sympthoms (headache, joint pain...) but my period is still not coming. My natural period would come 30.8. I read on other blogs that if menstruation is not coming in like 5 days, i have to visit gynecology. What should i do? Thanks for your answer.
