I know this has been done before, and that there are lots of bad things they don't tell you before you get pregnant.
But also, everyone goes on about how once you have the baby your life will never be the same again - they don't mention that you will love the baby so much, you will really like the new way, and not mind that everything you once enjoyed about your life has changed, because you have your baby instead.
OK, and then there is:
That you might never get the second trimester energy rush, and in fact might be exhausted all the way through!
That you will get instant attention from the NHS, until you get to 36 weeks pregnant, and then they will ignore you unless you can prove you are in labour (something that is impossible to do)
That you will never see the same midwife twice
That they will make you take home your wee, clean out the tub, and wee in it again a month later!
