Woah! You are already inching towards the twelve-week mark! Your body is getting used to the cute little visitor growing inside you and is doing everything to make them feel at home.
Your uterus is growing rapidly (now the size of a grapefruit!) even though it’s still in the pelvic cavity and your bump is not prominent to others. You will definitely be feeling pregnant though, thanks to the nausea and bloating.
If you have always exercised then you should continue doing so during pregnancy, provided your doctor approves of it! If you haven’t been exercising, then start with regular walks. Walking is the best exercise for you to begin with as it needs no expert supervision.
