Getting a seat on public transport or being allowed to jump a queue because you are pregnant is great. But have you had fellow commuters/bystanders ask you when you are due? And then calculate which trimester you're in and ask which doctor you are seeing and then hint that there are better doctors in that other hospital. Then proceed to size up your belly and give it marks- too big, too small, elongated or wide. Looks like a boy but could be a girl. And then notice you are sipping some sugary drink and remind you that you shouldn't be. And then start describing their whole pregnancy story, even if you did not ask.
But you know what, the more I think about it now, after having gone through this twice, I feel that it is only because this whole pregnancy, birthing and post delivery process is a really big deal. Like earth 'shatteringly' big. Everything about us and our bodies and our lives take a turn. And maybe others who have gone through it just want to connect with us and feel obliged to make our passage through it easier.
And many times even we want all the advice we can get. We want more than we can read online. We want to talk to real people who have been there and done that.
So my free advice to you is to take all that free advice you get with a pinch of salt. Smile, nod and then check with your doctor. And relax! We women are designed to do this. We rock!
