So fucking disapointed with ttc

Just need your advices, how to keep calm😣 We were TTC for 3 months, then I got pregnant, but had a miscarriage in January...this was the first cycle after mc, doctor put me on on some meds which will help to get pregnant (I have thin endometrium) and I had all the symptoms, nausea, exhaustion, AF was late for few days, even a vvvfl positive, which was an evap I guess. And today AF showed her ugly face, I was just sooo disapointed, I can not even explain that terrible feeling😭 I understand that I need just to relax, and dont think about it and maybe even stop TTC, but I just cant! I always wanted to have a baby at 20 years old, as my mom did, and Im already 25 and still not even pregnant..that driving me mad. Please help with any advice...or share your story of ttc. I just need to communicate with someone who is going through the same.
