I'm 7 weeks now and I experience tender breasts and fatigue, as well as nausea every now and then, though I don't ever throw up. My doctor said that's completely normal and some women go through their entire pregnancy without having a bit of nausea. It's still early though.
Ur still very early so some pregnancy symptoms may not show up until later on. But everyome is different. Some have nausea some dont. And your baby is still a very tiny little thing at this time. U may have spotting later on but as long as it isnt heavy or just a light pink color, then that is normal.
