Feeling discouraged

So me and my husband started ttc in September for our second baby. We got pregnant in February and miscarried at 8 weeks. It was absolutely devastating for us. We got the ok to start trying again in march so we did. And then today I started my period early and I'm so upset. We didn't have any problems conceiving our daughter, got pregnant within a month. I'm just feeling really discouraged. Everyone around me is announcing they are pregnant and I want to be happy for them but deep inside I'm so jealous and heartbroken. I really just needed to vent because everyone just keeps telling me it'll happen when it happens and I just can't hear it again!
