Feeling defeated

Can I vent a bit?🥺 been trying for a baby since September and haven’t had any luck, I know it’s nothing compared to some people but everyone around me is having a baby and announcing pregnancies. Which makes me incredibly happy for them and wish them very very well but deep down I feel more and more sad, for myself obviously. I have an OB appointment for my annual on Wednesday, hopefully we can see what’s going on 🤞🏼
