Bloating is VERY common in the early stages of pregnancy. Most women look and feel more bloated than they've ever ever been before, but it's normal and is just bloating - not the actual bump. It's caused the surge of hormones in early pregnancy. Just drink plenty of water and get as much rest as you can. It'll pass.
Im 7+4 and my stomach fells so tight and bloated i feel like i should be more like 12 weeks. Its just your womb changing getting ready for baby. As for feeling tired i sleep all night..wake up then feel like i need to sleep more so i stay in bed. The joys of the first trimester ha! Good luck and congratulations
