My last period was from Jan 30th to Feb 3rd. My boobs started hurting about half way through it. Which is a lil weird for me. I am on CD19. My boobs are still hurting. They always stop hurting acouple days after AF and do not start hurting again till AF starts. My next period is suppose to start around the 24th. I have been have some very light cramping for a couple day like AF is about to start. I have some clear watery CM its not a whole lot though. I am about 7DOP.
