38 weeks and throwing up

Last night I ate a hot pocket bc I noticed I hadn’t ate anything besides a big breakfast (at like 1pm) and it was already time for me to be asleep (3am) Maybe like 1 minute after finishing it I felt sick to my stomach and sat on the toilet trying to go #2. A little came out but other than that nothing. I felt nauseous so I decided to take a bath. In the bath I felt fine. Once I got out of the bath around 4 am I sat in bed and started feeling gross again. Couldn’t sleep till 6:30am I slept for maybe an hour until 7:30 and by then I had to stay awake since I had an ultrasound at 9:30am (not at my OB office) when I wake up this morning I have a little itch in my throat that I feel like I need to clear but everytime I tried to clear it I felt like I was gonna puke. Well it’s now 2pm and I was sitting on the couch and I tried to clear my throat when I suddenly vomited all over my blanket. Luckily it was just mucus. I ran to put the blanket in the washer and as I was walking I felt the need to puke again so I ran to the toilet and puked. This time it had a little bit of the food I ate earlier. I sat in front of the toilet and then again 3 minutes later I’m throwing up again. Does anyone know what’s wrong with me? Is it a sign of labor? I don’t have cramps right now but I did this morning. Baby is moving like crazy so he seems fine and was fine at the ultrasound. I don’t want to have to call my doctor for just vomiting unless it might be serious but the tickle in my throat is still there so I’m trying to avoid clearing it
