If down was a person

If down was a person it would be me... I have been trying for months after months to conceive but nope nothing has happened... I really feel like giving up but something is pushing me not to... I have 3 beautiful and healthy girls and one by my husband. I wanted to give him a second one but it hasn’t happened.. I have been tracking from taking my temperature and keeping up with my ovulation. It has become a Job. EVERYONE and I mean EVERYONE around me is PREGNANT. I feel useless towards my husband right now. I’m bomb and down.
