That feeling is the worst, and it only feels worse when you know that there are others out there who have struggled for years. This month, I made it through the TWW and kept my cool, but then my AF was a week late. So that whole week, I had convinced myself that I was pregnant and I started having "those symtoms". I took the first test 3 days after AF was due, but it was BFN. AF still hadn't come, so I didn't count myself down and out. Then after another 3 days, I took a test again and it was still negative. I clutched onto "sometimes it take more than a week to have enough HCG to register" then the next day AF arrived. I managed to get through work and just went home and cried. I had built it up so much in my head that it just hurt finding out there wasn't anything there in the first place.
I'm only on cycle 3, so I felt like it was wrong to be so disappointed. I had a few days where I was considering just giving up out of fear of having this experience get worse and worse every month. But in the end we decided to keep trying.
Where was I going with this? You aren't the only one to feel that disappointment so early on in your TTC journey. Seeing these stories of women who have been long term TTC and seeing some of the heartbreak makes it hard to validate my own feelings since we've only been trying 3 months, but don't push aside that feeling. Whether it's the first month or you've been trying for years, your feelings are your own. One person's experience doesn't make your experience any less important.
Also, don't give up. I'm holding on to the fact that when I'm finally holding that LO all of the heartbreak to get there will be worth it.
