Bloody discharge from nipple

Friday night I noticed some bloody discharge from my nipple. I went to see my OBGYN on Friday and she saw the discharge and referred me to a breast surgeon and put in an order for a mammogram and a breast ultrasound. I had both of those tests on Tuesday and they came back normal. Saw the surgeon today and she wants to do an MRI. I am 26. Never had any issues like this before. I have 3 children (7, 3, and 18 months). My grandma on my mom's side had stage 2 breast cancer and ended up having a double mastectomy and 24 years later she's still in remission. So, I guess my question is...has anyone ever had any experiences like this? What was the outcome? I thought when those two tests came back normal I was in the clear but apparently not. I can't help be panick.
