I don't have "lumps" as such. Its more just that there is so much stuff that makes up a breast, I wouldn't know what is normal and what is not. The link that Dach provided is helping me learn about my breasts and to familiarise myself with what is normal and therefore will be able to notice any changes in future.
I did my first breast check last night and just as Manta said, because I am on CD6 my breasts were a lot softer and nowhere near as lumpy as they would be later in my cycle.
