Freaking out possibly breast cancer?

2 months ago I saw a little blood coming out from my left nipple at first I was pretty sure it was from my tank top rubbing on it since I didn’t have a bra on and that went away never came back but I still went to the doctor. I did a mammogram and ultrasound, both showed nothing! But since I was having some bloody discharge from my left nipple the doctor referred me to a breast surgeon to get an MRI. I’m still waiting for that appointment but since yesterday I’ve been having some pain on my left breast kind of feels bruised. My toddler and my 1 year old keep digging their little elbows every time they go on top of me so I’m hoping it’s because of that but I doubt it’s that 🙁 I’m scared and worried.
