Hi ladies. Looks like I'm more then likely out for this cycle and I need to stock up on more opk's . Anyone any recommendations ?? I suffer from PCos so doing the likes of clearblue is out as it would cost me a fortune. I've been using an irish site that sold some cheapos but amazon seems to have loads of stuff at lot cheaper prices . Anyone know any particular good ones . Seen some that have apps on here. Anyone use them??
