I am either 3w 5days or 4w 5days because I ovulated on clomid around cd21-22 (unknown how long cycle us) and I was checking my cervical mucus just then and it is a very light brown colour... Could this be aftermath of implantation or early sign of chemical pregnancy? Next lot of bloods are being done Thursday to make sure my count is going up. My pregnancy tests are getting a lot darker from the initial one I did last Friday
