I had sex wid my boyfrnd on 21 october,he did not insert it completely though and it lasted only for 5 to 10 mins we did not use any safety,so i took unwanted 72 after 12 hours,but the next two days i had alcohol?so does having alcohol have any effect on its working? and my actual menses date is 1st,today is 30th october and i still didnt get my period,should i waif till 1st?or am i pregnant?and i have slight dizziness mayb which is due to the pill
