Diastasis Recti Stories/Advice

Hi everyone! I am 33 weeks pregnant and currently have a 2 finger separation at my upper abdominals and 3 finger separation at my belly button. I had a very strong core pre pregnancy, have maintained myself active during all of pregnancy avoiding crunches and anything that led to coning / doming but now I'm worried about this big separation! Today I noticed coning laying down with overhead arm presses and immediately stopped, but it's definitely coning in a more noticeable way. I am following all the tips but tbh don't know if it's making it worse! I am doing PT, as well a diaphragmatic breathing, and plan on taping immediately after my c section (have to have a c section given previous fibroid surgery). Anyway my question is -- how big of a separation did you have and how long did it take you to close it? Were you able to resolve your DR just with exercise and physio? Any tips? Thanks!
