Kitkat>> Cheer up, gal. Sometimes, things happen / don't happen for a reason. Actually, whenever I feel envious / jealous (Yup, I'm bad rite! But I guess it only shows that I'm human)about other people, I will try to remind myself that we won't know what the other person has gone through, her journey in life etc. Yes, maybe they may have conceived easily, but who knows, they have some medical problems, family problems etc. So try to count your blessings, and not your worries! I know it's so hard though.
From my experience, don't try to read into any of the symptoms. When we're TTC, we become so sensitive to all these symptoms. Who knows, these symptoms regularly occur even when we're not TTC, so we end up raising our own hopes, only to feel more disappointed at the end of it all.
I'm also in my 2ww now, and though I'm so busy at work, I still can't help thinking to myself daily whether I succeeded this cycle. You know, my record for my #1 and #2 were 2 cycles -- conceived both of them after 2 cycles. The rational side of me tells me that it's not going to be the same, cos' both me and DH are older now, we've got less rest and more stress compared to last time etc. Yet the emotional side of me wants it so much cos of my medical condition.
Btw, the truth is that no symptoms doesn't mean not pregnant ok. I was like that when I conceived #2. No sore boobs at all during the whole pregnancy. Ever since I delivered #1, I no longer have sore boobs.
