I just finished my regular menstrual cycle on Jul 28. I had intercourse on Sunday. But today I notice I was spotting. All day when I go to the restroom I notice as I'm wiping it's pinkish reddish and there is some clear thick mucus too. I have never spotted specially after just finishing a menstual cycle. Is the spotting in spite of ovulation? Or can it mean something else. This Sunday that i had intercourse he came outside of me. Should I be worried? From my understanding it takes time for a sperm to get to an egg so within a 3 day window can an egg be fertilized and start implantation bleeding or something? Do I need to take a pregnant test? Or can this just be left over blood from previous period?
