Once you've gotten your 1st period after pregnancy how long we're your cycles? I got my 1st period at 5 months (still EBF). It lasted my normal 5 days at a medium to heavy flow. It's been 45 days and still no AF. I have tested twice and got BFN both times. I was told it can be normal with breast feeding but to be concerned if it does not return within 3 months. I was curious if this is happining to any of you and how long before it came back.
