yes very much so everybodys different and react differently to pregnancy, some people having no symptoms others having all. this is just probuly normal for you so dont worry.
Yes.
Yes you can have sore breast within only 3 weeks of pregnancy, its has happened to me.
No. Just because your breasts are sore doesn't mean that you are pregnant. When you get your period, your breasts tend to get sore too. Sore breasts aren't the only sign of pregnancy.
ummm...yes...go get a pregnancy test.
You are pregnant more then likely
Yes
yes,you still COULD be pregnant. Not every woman has the same symptoms but nausea and tiredness are most definitely symptoms.
Yes
You very well could be pregnant. Get a pregnancy test if your suspect pregnancy.
Some women say they are sore, other women experience soreness with periods.
No
Both the times I was pregnant my breasts were swollen but not sore right away but only a pregnancy test will tell you for sure.
