Leaking placenta

Lauren • TTC#1 for 7 years. 2 failed IUIs, 1st IVF cancelled, Fresh Transfer#1 - BFP!!! We are beyond grateful! Baby boy born 08/25/18. FET complete with last embryo 06/20/21 - BFP

I was just told by my high-risk doctor that there’s a small placenta leak but everything looks great. Has anyone heard of this before?
