Sat down to pump tonight like usual and pumped nothing but blood from the right breast. Called the doctor and she said probably a burst blood vessel. I am not to pump that side at all and have to get an ultrasound in the morning. She said it could be difficult to recover supply afterward. I am going to continue to pump the left side. I have a freezer full of milk put aside and I was thinking of weaning soon so I am prepared for it to stop suddenly. I just didn't want it to end this way. I am so upset.
