So I was supposed to start on the 20th and it's now the 25th. The day I was supposed to start I had a light pink discharge and haven't since then. I've also had sore breasts for a week and a half to the point where I can't even get close to my nipples!! I was wondering when the best time to test or if I should at all. I've been having light cramping this week as well as a few days before I was supposed to start also suuuuuper moody.
