diastisis recti

Lina
Hi ladies!
I'm currently almost 31 weeks with my first baby, and the other day while sitting up from the couch I realized my bump did this weird pointy coning thing where the shape got totally distorted then went back to normal after I got up. Dr told me it's diastisis recti which all pregnant women get to a certain degree (I'm a personal trainer and have heard of it before) but none of my family members ever had coning this bad - so my question is - for 2nd time mums - have you experienced this and did your abdominal muscles go back to normal after having your LO?? Im worried as I read it can cause incontinence and lower back issues 

Thank you mamas!!
