Just feeling down !

I have been trying to conceive for the past 9 years and I am 31. Everytime a negative pregancy test or miscarriage. My employee and I are always discussing this topic because ,she has problems getting pregnant and we always get asked by people "when are you having kids,give us a girl" and they do not understand the struggle,pain,depression and anger. Today my employee came into my office to tell me she is pregnant a month after she got married. Believe me ,I am beyond excited for her,because it gives me hope. But at the sametime I feel sad like is there really a problem with me and I started crying.We have done all the necessary steps,semen analysis,ovulation testing,medicines, IVF is our last step.I told my husband and he said "when it is our time,it will happen and to stop crying".
