Expert answer:
There is always the possibility of error, but it is rare, most likely you are pregnant yourself.
During the relationship an incident occurred with the condom (day 30). I took the morning-after pill (day 31, 12 hours later) and the second dose 12 hours after the first. My period did not come. On the 14th day after the relationship I took the pill again and so far nothing (day 20). I took a BetaHCG test positive. Are there potential for errors in the result (hormonal change) considering taking the pill again?
