Feeling so down 😔

One of my best friends from college (who lives in another state but I still keep in touch with) had an early miscarriage in October. They had just started TTC in September. Now, she just texted me the happy news that she is pregnant again, due in July (so she conceived ASAP after her miscarriage). I’m so happy for her, but it just makes me so sad that it hasn’t happened for me yet. My husband and I have been trying for 7 months with no success. I have super regular cycles and ovulate at the same time each month. He’s had a SA which came back fine. We’re also young. I just don’t understand why it’s not happening for us. 😢 We have another couple we’re friends with (that lives out of town) who out of the blue asked to meet up in two weeks. I know they’ve been TTC too, and I’m really going to struggle handling it if they tell us they’re expecting too...
