cant get pregnant

hi. I have been having trouble getting pregnant. we do it everyday 3 times a day sometimes. I am 41 and he is 40. does any1 else seem to have problems or suggestions? i do have fibroids but my doctor doesn't do anything. I also have 2 cysts that they say will go away. and me n my boyfriend are restarting our lives together. we were married 17 yrs ago and then divorced and recently got back together. we have 2 teens together but want to have another 1. he is getting frustrated because I am not pregnant after 3onths of trying and I'm upset cause I want this also.
