First Trimester Mornings (looking for some advice)

Hi! First pregnancy. I'm a 21 year old college student so I'm used to early classes. I'm about 8 or 9 weeks and the past week or so when I awake in the morning I almost feel a heaviness on my chest that I've never experienced before. I've also been expereiceing nausea throughout the day but I know that's normal. Hoping for some advice from other moms who have felt a weird almost off beat breathing time in the early mornings. It's nothing to where it seems serious, just an odd feeling. Thanks in advance!!!
