So my husband and I were doing the deed. I laid around for like a half hour afterwards then got up to pee and his cum came out of me and it was light pink then I wiped and it was light pink. I'm cramping and have been but it's dull annoying cramping, nothing too painful. Then I peed again like 20 minutes later and the picture is how it looked when I wiped. I'm 4 weeks 3 days pregnant. According to the implantion calculator, my baby should've implanted December 4th so I'm not sure what this blood could be from? Help!!!!
