A few days after conception, it is normal for a woman to notice a white milky discharge from her vagina due to the vaginal walls thickening, according to WebMD. As the cells that line the vagina continue to grow throughout pregnancy, it is likely that the discharge continues.
WebMD notes that this discharge is called leukorrhea. In addition to the discharge, shortly after conception, a woman may notice light spotting as a result of the egg's implantation and cramping that is often mistaken for menstrual cramps.
WebMD advises that women can wear a panty liner, but never a tampon, to feel more comfortable when experiencing the discharge. Also, women should always consult their doctor if the discharge is green, yellow, foul-smelling, or extremely clear and thick.
