Desperately trying to conceive

I am married to an older man that is 45 yrs old and I am 32. We have been married for 5 yrs with NO luck of being pregnant. He is very old fashioned and has the mind set that Dr intervention is not needed......I want a baby so badly but sometimes I feel that I am the only one trying. Plus having sex is rather difficult at times because I work during the day & he works during the night. If anyone else has gone through what I am currently going through right now,please share ur story with me.
