I am in the same position so I feel you - 1.5 years trying, not even a touch of a faint line and everyone around me is on baby #1, 2 or 3. I think the best and only thing you can really do is try to focus on getting tested to see if there are any issues with you or your partner and consider then trying IUI/IVF. Try to do nice things for yourself- eating well, exercise, spa, making plans with friends etc. You are right - it is impossible to know if it will be possible- all you can do is explore every option to give yourself the best chance possible.
Oh lovely, sending big hugs ❤️ It’s so rough when you want it so much and it doesn’t happen straight away. I don’t know where you are in terms of either the world or your journey but if you ever need an ear… xxx
