Don’t know what to do :(

Im 3 days late I’ve bad migraines the passed few days and I kept throwing up to the point where there’s nothing but stomach acid sorry for tmi and yesterday I had the worst back pain 😩 but I’m honestly scared to test we had been trying for 3 years and kinda gave up trying a while ago. I just don’t want to see that negative line. Has anyone else in a situation similar to this ? 😞
