titty grow once fast now slow

i've been on e for 4 months

in the first two months my breasts began growing immediately from flat chested to budding to filled out, small cup breasts

but, although my areolas still hurt, there hasn't been any visible growth at all throughout the last two mo's

i guess i'm worried because i keep reading that growth happens slowly and ramps up, but it feels like it's been the opposite for me. so i can't tell if it's all in my head and i should sit tight, or if i should change up my regimen?
