Ummm So I Just Lost My Virginity 2 Days Ago Yesterday I Had Spotting Now Today A Lil Bit Of Yellow Stuff We Had Protected Sex So What Does This Mean ? ;-(

You could have irritated the walls of your vagina, causing spotting. The discharge may just be your vaginal fluids. It could be something else.

NOTHING is 100% effective against pregnancy (although it is far too early for signs to be obvious).

Protected or unprotected, I trust you asked your partner about his sexual history and possibility of STD's?
