Pregnant - breast lump

Hi beauties , I’m wondering if anyone has been in the same situation, I found a breast lump at 18 weeks and had an ultrasound, it came back non suspicious likely fibroidenoma , I had another one at 32 weeks which showed it had grown but still non suspicious, I am now 38 weeks and feel like it’s changed and is now lumpier , I am so concerned and my Dr has said wait until after I have Bub to see if it dissapears . I am a nervous wreck though 😥 thank you
