This is my chart anyone close to me? Also has anyone had horrible cramping and back ache on cd19!!?! Today has been horrible for me. I've been having intense cramping with lower back ache almost like a mild contraction. Not sure why so just wanted to see if it's kind of normal lol ✨🙏🏽✨🚼✨ BABY DUST LADIES✨
