What is everyone trying/doing?

Jessica • My name is Jessica. I am married. We have a 9year old son and a daughter who is 2!
Just wondering what everyone has been doing to ttc. I just feel like there is too much work and money cost in trying. I feel like I am going crazy. I have O test, pregnancy test on hand, having sex everyday with my DH sometimes more than twice a day sorry if that is TMI lol. What more can I  do? I have a five year old that will be six this summer and we never tried for him it just happend so I am on the other side now try to have another baby. Is there something I can try out there? My husband and my fertility has been checked and it's great so I just feel stress, tired, confused but don't want to give up!! Any ideas or advice would be great!
