In one month I take two unwanted 72 pill

8 march i got period , afterthat in 16 march i take unwanted 72 pill within 12 hours of unprotected sex with my husband , after one week of taking theke pill i have spotting problem, last 4 april and 5 april i have heavy bleeding like period , again from 8 april I had transparent type discharge like egg white , 9 april again we have unprotected Intercourse, so i take unwanted 72 pill again within 11 hours of intercourse . If here any chance of pregnancy? Im confused about my period, is 4th or 5th april is my periods day or not? Because normally from teenage in my period time 1st and 4th day have very less bleeding, and 2nd and 3rd day have heavy bleeding. After having unwanted 72 on previous month the bleeding ,spotting stays upto 10-12 days , now im confused. In my 4 Yr of marriage I take unwanted 72 several times, all time after taking this pill I have spotting , and i have no issue with period, I got my period on proper date or 1-2 days before or after of the period date .
