Hello Doctor, On Exact 30th Day Of My LMP I

Hello doctor,
On exact 30th day of my LMP i consulted my doc nd done UPTwhich came negative hence she advised me to take meprate for 5 days to get my peroids. I completed my dosage in 5days(34th day of LMP) and we had unprotected intercourse on 6th day. So, i had to take emergency contraceptive on next day morning to avoid any complecations. After 12days, i again consulted my doc as i dint get my period nd told about the incidence. Then again i went through UPT which came +ve. Now, since i m two nd half mnth pregnant, i would like to know when did the conception might have occured?(I have been told that the delayed conception has occured) Will there be any problem during my pregnancy because of meprate that i took?
