Well, I got headaches almost right away. I would have to say about a month into the pregnancy. My breast were tender about 2 weeks after I conceived. I didn't get the flu like symptoms until I was 2 months pregnant. It lasted for about 2 1/2 months. Weird thing was I only vomited when I brushed my teeth in the morning and at nite when I would eat dinner. I didn't have any food cravings at all, but I started having food adversions when I was 2 months pregnant. Everyone is different. Some people are sick through their whole pregnancy, some don't get sick at all. Good luck!
