For the record, I want to say that the second trimester of pregnancy can be really great. I am saying this because I'm bound to forget it over the next few weeks.
It took me quite some time to want to revisit pregnancy after the last one - I always planned to (and quite a bit earlier than this, obviously) but until Liam was over two, I didn't look forward to it. The people who were ready to go again after six months or so left me quite bemused.
Having now experienced the better part of another pregnancy, I guess I mostly remembered the first trimester last time (ie weeks 5 to 18 or so, in my case). The tiredness and nausea of course, but I think the feelings - the depression basically - was what stuck with me, even though I wouldn't have articulated it that way at the time. And yeah, that sucked again the second time around.
And now, I'm well and truly into the third trimester - 31 weeks today in fact - and definitely getting more uncomfortable. I have the same abdominal muscle pain I had last time, which as I recall, just gets worse each week until birth. At this point it is a relatively constant irritation, and hurts quite a bit if I bend over, stretch it at all, do anything that requires extra abdominal work, lean forward over the counter etc. Plus I am now just constantly bumping into things and sleeping less and less well.
All in all I'd have to say I'm still enjoying being pregnant - and am very conscious that it may well never happen again - but it's definitely not all that comfortable physically.
So just in case by the end all I remember are the hard bits, this is my reminder to self: Second trimester was really quite lovely.
