Sore boobs, not sure how to feel about this.

For a few years now I would have a soreness come and go in my left breast, 8 years ago I went to the doctor for this, I was 19 at the time. They said they would not do a mammogram because of my age, so instead they did an ultrasound and found nothing. They wrote it off as a caffeine deposit and I should cut back on sodas and teas.

Here I am again, having this feeling but it has gone from the usual soreness to a stabbing pain every now and then.

I recently got my ear pierced on my right side so I've been trying to keep my daughter from pulling on it, I carry her on my left side now. Since shes teething and going through a leap I have to carry her most of the day, every day, because she just cannot be away from me or she will scream for hours. Shes nearly 25 pounds.

Its exhausting, I'm stressed, I'm a stay at home parent of two, my husband doesnt help at all in the evenings so I do everything around the house and clean after him.

Am I pushing my body too hard?

My mother had ovarian cancer, then breast cancer and now shes having biopsies for lymphoma and skin cancer.

I feel like I'm being paranoid because of what's going on with my mom and the stress of being at home with no one to talk to is getting to me.

I dont feel a lump but I'm so afraid to go to the doctor. I know I should, but my head is filled with so many "what if's."
