I'm sorry to hear that, mumface
Although tbh, I feel the same as you! I'm currently CD27 (just had to work that out!!) and feeling as though the witch is right around the corner. I've been stupidly hungry recently as well...maybe it's the up and down weather?!
So, yesterday morning, when I went to the bathroom, there was the smallest amount of pink CM, but only when I wiped. I panicked, because I thought AF was here, and spent most of the day after that crying my eyes out, because it's my lat drug cycle. I just felt so defeated. But actually....nothing since then? It was literally just that one time, and I've been checking ever since but absolutely nothing! What is going on?! I never spot before AF is due anyway, which is why it was quite heartbreaking. AF also shouldn't be here until friday/saturday, because on letrozole my cycles are 30 days. So what was that for? I don't particularly feel like it could have been IB, because it's wayyyy too late for that...I think? The only thing I can think is that, if it WAS IB, then it won't stick because by the time it gets to releasing enough hormone, AF will be here and ruin it.
I'm sure I'm looking way too deeply into this. I'm not ready to give up yet, but at the same time, I don't think I'm ready to be crushed again.
