Feeling horrible

Keymi
I took 2 pregancy tests, they were both positive. My period is late by almost two weeks, so I think I'm clearly pregnant. I feel horrible I don't want to get up from bed. I have stomach aces , very constipated and I'm nauseous all the time. Vomit from time to time. I'm a full time student and graduate May 16. 
Is there anything I can take or do to make the symptoms better ?
