Yes, I had heaps of trouble breastfeeding on the minipill too. I really dont know how it affects future fertility, although, like the other ladies have said, it's been around and lots of studies-- so I'd assume it's ok. On a different note, my GP has always told me that the mini pill is less effective as a contraceptive than the normal pill- so be careful if you dont want to concieve too soon . It's apparently REALLY important that you take it the exact same time each day (within an hour, from memory). I know they say that with the normal pill too, so I didnt really think much of it when my OB told me to take it same time each day, but apparently with the mini pill it's absolute necessity for optimal protection.
Sorry I didnt really answer your question, but HTH anyway
