Or at least give them a call and see if it's a normal side effect of the hormones. I wish I knew enough to tell you not to worry, but if I were in your shoes I would be worried too. I suspect it's just colostrum, which in and of itself isn't worrying, but it does mean that your body is thinking that it's pregnant. I think. I'm not a medical doctor so I'm the farthest thing from an authority on this.
In short: Yeah. Call your doctor. 🙂
