We had intercourse on my 2nd day of menstruation it is possible for me to get pregnant.. ?

No: If it was your period, having sex then would not lead to pregnancy. There is no egg growing and ovulation is likely at least 10-12 days away!

Unlikely: Unlikely to get pregnant if it is accurate that it is the 2nd day of one's menstrual cycle. However, it is not uncommon for a woman to have bleeding in between cycles (not true "2nd day of cycle"), and thus, possibility of pregnancy exists. Thus, if trying to avoid pregnancy, best to use contraception.

Unlikely: Ovulation usually occurs 10-14 days before a period starts. Fertilization can occur with intercourse up to 3 days before ovulation.
