When does the placenta attach to the uterus?

The placenta starts to grow upon implantation of the fetus into the wall of the uterus around week 4 of pregnancy. The placenta is believed to have established full maternal blood supply and attachment by the end of week 12.

Tbh i think it’s an odd coincidence, maybe you “predicted the future” it’s happened to me before but i wouldn’t doubt it if you did but i hope you have fun
