advice?!

Be
So today is cycle day 57 my longest cycle was 56 my shortest cycle was 32 so my average cycle is 44. I have been experiencing cramping and nausa. I get dizzy and hot flashes fast and this morning I all of sudden got nausa and threw up yellow stuff. I don't know when to test since I have irregular cycles that varies from 32-56. I'm 18 and ttc for over a year. I'm scared to test because I don't wanna get my hopes up. Any advice?
