I've been bleeding lightly since last sat. and my period is due this sun. i have 2 more pills and on sun. sugar pills start. my vagina burns a lot?

Thanks for asking!: Bleeding is common in pregnancy or pregnancy related complications, although breakthrough bleeding need to be considered too, du to her pills. I will recommended a blood test asap.

Vaginitis: If you did not miss any pills this cycle, and had the break through bleeding, along w/ burning, suspect vaginitis. Try Monistat over the counter. If not better, see gyn.
