From what you have sayed it was there. Now you dont notice it, cant see it and dont feel it?? If thats the case I would crack on with the cycle. You can always stop at anytime and if its went away once it will go away again.
Just what I would do in the same situation tho. Wish you luck with it. Hope all goes well and you can run your cycle. I think you should too.

some days it seems easier to feel than others...on days when i'm not sure if i can feel it i think it's just a chunk of my boob meat.
the lump is not directly under my areola, it's a few cm below, and it doesn't nor never has been noticable or caused any nip puffiness
