bad news

Im about to end my ttc mission. We have been trying for 3 years now. We had gotten pregnant only to lose the baby last year, and today i got news that there is a problem with my reproductive system. i dont know what to do. Do we keep trying untill we for sure know there is no hope? Or keep trying only to find Its not possible and be heartbroken... 😭 We just cant keep getting our hopes up. Its killing us.
