there is an ingrediant in some cough medicines called guifaston (not sure of spelling) which increases egg white cm. it is recommended you take it when your ovulating to give the swimmers a better chance of gettting to the egg, asda, sainsburys and tesco do there own brands but also meltus, venos and lots of other "expectorants" have the ingrediant and if you read back on this thread a few people seemed to try it and it worked, so i might get some for next cycle.
