I guess we'll just have to wait and see. I don't think I want another baby this soon though.
My ob told me that we're most fertile around the 6 week mark too. Regardless of breastfeeding.
7-14 days to test, you can start getting faint results about seven days. That is about when I tested.
I have always heard you are most fertile the 6 weeks After having baby.
It is rare to ovulate that soon after baby. Takes about 2 weeks to get a positive test.
