Okay im on CD9 today. AF finished on CD6 and it was only very light spotting. CD7 and 8 was just a bit of dry CM but today i have creamy CM and it had a streak of blood in it! and i have had a bit of cramping and a slight bit of back pain on the lower right side. Does anyone know what the blood could be from?

Sorry for the detail Im just confused, god ttc is stressful!
