Talk to Gynecologist on Inducing Periods

Kindly share as anonymous Me and my husband had sex and half way later we used protection. After the deed i asked him if there was precum. As we will be moving from here so rn we havent decided on having a baby. Though the chances are very low of concieving as i took ecp(emergency contraceptive pill) but that was just when 72hours window was about to end. So will the ecp work for me when taken this late and secondly i would like to know how to induce periods. My last periods were on 31st july. I’m worried. This all happened when i was in my country so to be on the safer side I bought primolut N. Which i dint take as yet Help needed. Thanks
