Actually, it concerns my gf. We have had a sexual adventure on the 6th, and just to be cautious, she took a Norlevo birth control EC pill. She was supposed to get her period on the 5th but i guess because of emotional stresses, it got delayed. Her last period was on the 3rd of December 2010. Yesterday, 7 Jan, she got a little yellow vaginal discharge and a bearable clitoral pain. She is sometimes getting nausea and several time got a belly pain which lasted not more than 5 minutes. Is all this normal? Her parent are not aware of her taking EC pills and she doesn t want them to know.. Hope to find a answer here.
