I am 21 years old unmarried girl. I have never sexual intercourse. I have very irregular period for 5 yrs. It comes even in more than two months. My last date was on 23/11/17. On 1/1/18 my boyfriend just touched his glans penis in my hymen for few second, then removed.. On 16/1/18 doctor checked in prega news. It showed a faint line..she told me as
pregnant.. She prescribed me ETHINORM E and ETHINORM P for 3 days. I have taken in two days . How can I prevent pregnancy.
