purpleaura - in a rush but had to repsond!! I, like you, was in a total state about the actual pregnancy bit before we started ttc, so much so that we put it off for years months before I dared start! I was in a panic about the body changes (have had eating disorders in the past so body image is a major issue for me), about the lifestyle changes even before the baby comes, about work, about money... everything!!! Cried when I got the BFP (not because I wasn't happy) because I was sure my life would be awful from then on!
In all honesty, since then, it has been manageable to very good! Nausea kicked in at week 6 and lasted til week 12, that was actually truly awful (I felt unlike myself and a zombie) but HONESTLY it was still manageable IYSWIM. Yes I felt hideous but I knew it wouldn't last forever and somehow I did get through it. That's not rose-tinted glasses, I won't lie and say it was anything other than vile, but the anxiety about it advance was worse than the reality.
Since week 12 I have felt literally amazing. Energy is back, nausea gone. THen of course in the last few weeks (am 24+5) I have started ot get suddenly much much bigger in the tummy. Yes, I have been a little freaked out about this, I can't deny. I had a couple of days where I was stupidly really down about it and felt my body was out of control. But even that has lessened. I have bought a couple of flatteirng maternity tops and dresses which have made me feel like I am still hanging on to 'me' and not just slobbing about in fat day clothes. I still can't say I absolutely adore my growing tummy but I am AMAZED that I am now not really at all bothered by it.
Thought I'd be freaked out by feeling kicks (I am that much of a control freak!) but this part I absolutely LOVE.
So from someone who was truly dreading it (and I am aware that I am fast approaching the end of the nice 2nd trimester!) all I can say is that for me it has been a really pretty good experience on balance. I assumed I would be in a permanent panic but I think some hormones have kicked in and I am much much calmer than I thought.
Oh, and I have had pelvic girdle pain - which has sucked - but even that hasn't blighted the whole experience for me. Again, is just something else to get on with and manage.
Hope that helps and good luck!!
