I've had different doctors for each of my pregnancies and they all thought differently about trimesters. I usually go with 13 weeks- 2nd trimester and 28 weeks - 3rd trimester. So, no they're not 'even' trimesters but thats been the most common dividing I've come across. I wonder what my new doctor will say ?!
I think it always seems sooooooooooooooooooo long when you're in the first or start of the second then time starts to whizz by. All of a sudden it dawns that this baby will be born sooner rather than later and it becomes 'how much time do I have left ?' My third pregnancy I worked right up until she was born and I remember lying on the delivery table thinking 'it's too soon, where did the time go ? Someone's made a mistake!'
I can't conceive (hee hee) of a third trimester right now. My current dilemma (and its a nice one to have) is when to tell. The only thing that makes me want to tell is the kids. They will not be able to keep it a secret though, so once they know, everyone will. Ideally, I'd like to tell around 16 weeks maybe, but its so hard hiding DR appts, ultrasounds, and secretly looking at baby stuff in the shops from them ! I think my oldest (10 going on 25) has seen hpts in the bathroom and suspects something, but so far hasn't said much beyond 'it would be so cool to have a baby, Mum'...
Also, the few people I told about my miscarriage were less than supportive so i don't think I'm going to get much reaction about this pregnancy. I like keeping it secret, it's precious ! Most of the people I know right now have little children, babies and toddlers. Even though I'm the same age or younger than them, my kids are older and they seem to think they were born that age and I have no understanding of what it's like to have little ones. One of them will be crying or having a tantrum and they say 'oh you have no idea what it's like ! i'm exhausted blah blah blah' I used to keep quiet but now I just let go. Most people I know with little kids think that what they find difficult or stressful now is magically going to stop when their children reach a certain age. HA ! It doesn't. I've had babies, I've raised toddlers, I know what its like, and no my kids aren't 'easier' because they're older, they're just as hard in different ways ! And as for that magic 'school age', thats when it gets truly tricky because thats when they make friends, really strike out on their own and start having full on schedules. It makes me look back on baby days and think 'oh that was so EASY!'
Wooooooo, sorry for the rant. You can see this is one of my pet peeves right now ! And some hormones talking... The worst part is, I could keep going especially about this committee I'm on.........
Ok, time for some chocolate and a lie down.
