Breast lump? Kind of freaking out …

Has anyone on here had experience with a breast lump and it not be cancerous? I am 26, about to be 27 in a few weeks. I went to my obgyn about a month ago due to having sore breasts for about a month (usually I have bad pms soreness but it goes away by the time my period starts). In January I started my period and my breast tenderness never went away, and it honestly still hasn’t almost into March at this point. They sent me to get an ultrasound and mammogram, which I had yesterday, and although they couldn’t find a reason for my overall tenderness, they found a small lump in my left breast. She said given my age , it isn’t likely cancer and probably just a fibroadenoma, but there still is a chance so they are doing a biopsy on it next week. I’m just super frustrated as we are currently TTC baby #2 and I also have endometriosis and PCOS, so I feel like I’m just getting bad luck with my female health 😩 I also just had a chemical pregnancy like 2 weeks ago and I’m tired of all this bad news. Anyway, anyone else need to get a biopsy and everything turn out okay? I’m just feeling defeated right now.
