Ways to concieve?

Is there anything I can try?... my fertile window is between the 2nd of Feb and the 8th of Feb. Been trying for a year now and nothing. We don't smoke and barely drink. We take our vitamins, eat healthy, is there different positions that we can try or is that a myth? Has there been anything you have tried differently then conceived? Every month is heart breaking. My partner is 41 and I'm 27. Can the age gap be something to do with it? Thanks in advance 💞
