People are so differnt when it comes to pregnancy. I think morning sickness can show up as early as 3 weeks or it may not show up at all. I only had 4 or 5 cases of m/s (by the way m/s can show up at any time of the day not just in the morning)
You should call a Dr. about the spotting. It is fairly common to spot but anything that concerns you should definatly be checked out by a Dr.
As far as showing goes..it just depends. I am overweight and 19 weeks pg and I am not really showing at all. Some people show early and others won't show until later on.
Hope all goes well. Keep us informed and welcome to the boards. There are a lot of people here that can help
