Normal. Most women's breasts are "lumpy-bumpy", especially after pregnancy and breastfeeding. Rest assured that you are normal.
Have lumpy breasts before period, after the lumpiness is there, but much less. Do fibrocystic lumps need to disappear or just increase and decrease?
Decrease in size. Fibrocystic breast disease is a common condition. Usually women will notice an increase in size and discomfort before menses (approximately 1-2 weeks prior) and a reduction in size and discomfort with the menses/period.
