I had unprotected sex the week of my ovulation. We used the pullout method. He pulled out a while before he was going to cum each time. It has been 7 days since then and my period is due in 7 days. I woke up with light spotting (pink, bownish). This subsided after a few hours. I am now very stressed and worried this could have been implantation bleeding. I was considering the Vitamin C method in stopping the pregnancy if there is a fertilized egg. Could you guys please help me and give some advice? Does it sound like I could be pregnant? Any effective ways to induce my period or stop the pregnancy?
