I'm so confuse 🙁🙁🤷🏽‍♀️🤷🏽‍♀️🤷🏽‍♀️

So today while I was at work . I use the bathroom and when I wiped. It was pink spotting . Now it's been a week since my period . Could it be implantation ? I did have sex during my period .(last few days ) he came inside . Could it be that I ovulate right after my period? How long does Sperm stay inside? I'm not ready for a baby but I will be happy and take responsibility . 😁😁😁😊😊😊 but I just want to know if anyone ever experience this? Like ovulate right after period !!!! I thought be a week before that .
