test again?

i took a test a few days ago, maybe like tues or wedn? but it wasnt first morning pee, and it also could have been taken too early? but it came out negative, the thing is im still having the same symptoms as before. my breasts are still tender, (im unusually gassy), i get bloated after eating something as small as an apple. and i typically can go without breakfast in the morning without feeling that hungry, but now when i dont eat in the morning or whenever i get hungry, i start feeling nauseous. and ive been getting headaches more frequently. should i test again?
