My sister had sex for the first time with her husband. He did not use the condom initially but thereafter. She took pill 5-7 hours later. Post sex, she has been experiencing a lot of discharge (light yellow also). First few days she had irritation. While discharge has reduced to some extent, her discharge has been more than even after 6 days. Is this normal? Could this be side effect of ipill or a sign of
STD?
