My advice before you get pregnant would be to cherish the last few days/weeks/months where you can just enjoy life without having to be responsible for another human being! TV programmes, films etc show pregnant women glowing and wandering around without a care in the world but this is not the case at all! The moment you see those blue lines appear, you are responsible for somebody else for the rest of your life and with this responsibility comes a lot of worry!
In my experience the first few weeks were hard once I found out i was pregnant because until you get that first scan you worry about symptoms or lack of symptoms, whether or not to tell people before scan etc, which doctor to choose, which hospital to deliver in. Then you worry in between every scan after that. Once the baby starts moving you are counting kicks etc. In the back of your mind always is the worry about the impending labor and birth experience!
Then once they are born the fun begins! You worry about feeds, poop, temperatures, sneezes, reflux, bottle or breast, feeding, weaning,cloth or disposable diapers, sleeping etc. Then when they get older it is schools, friends, activities, travel, holidays etc and so it goes on and on and before you know it your child is 7 and you realise that in that 7 + years you can honestly say that you have never really had a decent nights sleep since you saw those two blue lines!
I have two children and absolutely adore them and I would not change a thing about the experiences we have had so far and it had been an absolute joy to have them in my life. I learn something new about them and myself every day and it is so much fun to watch them grow, reach all their milestones, see their little personalities develop etc but I wish somebody had prepared me for the worry because I would have slept for a few months before getting pregnant!
Good luck!
