Bleeding in first time sexual intercourse is quite common & it is due to rupture of hymen
. As bleeding was mild and stopped completely, then you need not to be worried as it heals automatically in 2-3 days. Consult with your doctor if bleeding continues beyond 3 days. Also it does not signify normal period bleeding.
Practice safe sex
by using safe period/Em Pill/Condom etc to avoid unwanted pregnancy
& vaginal bleeding.
