Can this be a pregnancy symptom ?

So last night I woke up & felt like I had to throw up & it was so hot in the room but not extremely hot & after I had been sitting up for about 10 minutes I felt like I wasn’t able to really breath & felt like I was going to have a panic attack now on my way home I almost wanted to cry & was shaking a little now can that be a pregnancy symptom? My boyfriend said I’m probably pregnant but I just want to see what you guys think? I even have been cramping very lightly the pass two-three days
