Birth Control Help!

Look, I am 20 years old, my period is pretty irregular. I am a salesman so I am constantly on my feet, trying to look happy. I am currently not having sex, so I asked my gyno for BC that would help with the horrible cramps. She put me on Springtec, and it made my life ten times worse. I only took it for three days, and was so incredibly nauseous, migraines, and very shakey. I had to take off more work, and am now not even taking a BC. Any advice? Anything you ladies use (bc, or even tips to combat getting sick from bc) thanks in advance!💕
