birth control
"I started taking this at 6 weeks post Partum for birth control while nursing. I feel like I have had a period now non-stop or I just have spotting and no idea when my actual period is due anymore. I've quit trying to figure it out; obviously I'm annoyed! It's supposed to not bother lactation, but there has been a definite decrease In my milk supply. Planning to finish this pack out and quit and use a backup. I would rather have no birth control pill at this point than all this spotting constantly! 
Also, I have been noticing a change in vision, but I have blamed it constantly on my contacts, lol! Seems to be a common side effect- maybe that's my problem!"
