Pregnancy is a scary time
You spend the first 12 weeks almost too afraid to breathe
You get to 16 weeks and hopefully can breathe a little easier if you get to hear the heartbeat but you know you still have the 20 week scan to get past
You get the scan ok and then think. "I hope I can get to at least 23weeks" as you know the baby will have a fighting chance of survival
Then it's "I hope I can get to 28 weeks" as the baby's chances hugely improve from that point on.
Then 37 weeks so that you have a term baby and hopefully no complications
Then you hit 40 weeks and really pray that the baby comes soon as you can't breathe, can't sleep, can't walk, need to go for a wee every 2minutes (but only manage a tiny dribble) and you really want to meet this new little person
Hopefully we will all be done by 42 weeks!
