I'm not sure about this one either.... It took us just over 2 years to conceive Zander & I was booked for induction at 41wk 4 days (so 11 days over) and there was no question about placental function at all. I'm not really sure I understand why there would be a link to time TTC & placental function, it's not like the placenta is there for the entire time you're TTC, it's only there during pregnancy the same as any other woman.....
