My periods ended on sunday(6th april) and I had sex on wednesday i.e 9th of april and then on 11th april Also.. But my bf didnt left the sperm inside.. Bt i think a drop or two drops were left inside. And today it is 14th april and i noticed a very light brown colour in my discharged white water from vagina. Is it a sign of pregnancy or is it just normal? Can 2 drops of sperm cause pregnancy? Pls reply.
