I will be 22 weeks pregnant on Friday, and apart from now getting a little bump, I have been fine all the way through my pregnancy, and as its my first Im glad because it wont put me off :-) Had scan last week and we found out we are having a little girl.
I just thank myslef lucky that I am having a brilliant pregnancy. It wont be long until your 12 week scan, try not to worry.
my 2 pregnancies were totally different, 7 weeks is still early and you may find that you dont experience anything at that stage. Not everyone gets morning sickness etc.
both my pregnancies have been complete opposites kitten so i wouldnt worry to much. when i was pregnat with my son i had no symptoms whatsoever, infact i didnt start to show till i was 6-7 months and even then i was small. However with my daughter i had sickness throughout the whole day, bleeding for 4 months, heartburn, leg cramps.
for me the sickness started at 9 weeks and didnt stop until 16weeks or you could be one of the lucky ones who feels fine all the way through, try not to worry too much
