Can any of you ladies who have had implantation bleeding, please tell me what it's like? I ovulated on Day 14 and have had light blood when I wipe since Day 21. I'm now Day 24. Did a First Response Pregnancy Test yesterday 9DPO and it was negative. I've never had a 21 day cycle. Could this be implantation bleeding and it's just too early to show up on a pregnancy test or do you think it's just a very early period. Last month I had a 25 day cycle. Thanks!
