So as time goes on, I am stressing out less and trying to go with the flow," she added.The 35-year-old reality star also shared the details about how her conditions affected her first pregnancy with North."We induced my labour and I had North soon after. Right after delivery, the placenta usually then comes out. Mine did not. My placenta stayed attached inside my uterus, which is a condition called placenta accreta...""My doctor had to stick his entire arm in me and detach the placenta with his hand, scraping it away from my uterus with his fingernails. How disgusting and painful," she wrote.
