Concerning lump, but ultrasound in a week and a half normal?

First of all, very grateful for this outlet.

I found a small, hard lump in the outside of my right breast a few months ago (slightly smaller than a pea), and being in professional school, moving cities, and changing insurance, I put off getting it checked. It also just seemed so superficial, pretty mobile, and smooth. I just wasn't incredibly concerned.

I had an appointment with my nurse practitioner 2 days ago thinking she would tell me it was nothing to worry about, and, of course, I'm here, so that is clearly not what happened. I have an ultrasound 3/18, and I am dreading this week + of waiting.

I am only 26 years old. I do check some boxes for risk factors, though, unfortunately: family history of bc (maternal grandmother, maternal aunt), family history of prostate cancer (maternal grandfather), low vit. D (8 as of a month+ ago), early-ish first period (11).

My appointment was Tuesday, and the breast center can't get me in for an ultrasound until 3/18 (almost 2 weeks). My question is: Should I see if they can get me in for an ultrasound any sooner?

Because I’m on group insurance connected to a university and have to have a referral from the university health center, I don’t know that I have much of an option to go somewhere else. I may have to go to the university’s breast center, but I guess it is worth asking.

Also, some things I’ve I noticed that may/may not be related that I found interesting:

Increased vasculature of my right breast compared to my left. I have always had somewhat 'veiny' breasts, and from the front they seemed relatively comparable. But when I turn to the side, the outside of my right breast has a lot more visible vessels that appear larger and that virtually all to lead to this bump. It makes so much sense to me as a symptom.

I also have developed a much stronger odor in my right armpit in recent months. It almost smells like 'stale' BO and happens so quickly after I shower I find myself reapplying deoderant multiple times a day.

About a month and a half ago, I developed a stress fracture running and had my vitamin D levels checked. I had severe vitamin D deficiency (8).

I've also been stressed and drained, but I am in veterinary school, so that is to be expected.

I have always had trouble focusing and memory problems, but in recent months, it has gotten to the point that it has affected not just my school/studies, but my relationships. It has been very frustrating to me and those around me. Last month I decided I had to do something about it and went back on medication for ADD (which I am not a fan of).

Thank you for providing a special forum for people like me. It's hard to process while not having answers. Sometimes I feel like my fear is an overreaction, and I also find myself not talking to anyone about it for fear of worrying them. I have told my fiance, but I basically said it's just a precaution and it's most likely nothing, which I know, statistically speaking, is true. But it doesn't help the constant anxiety I feel. (Side note: I am seeing a therapist tomorrow to vent and have a no-judgement conversation about my fears.
