Nauseous sore breasts constant urinating but negative pregnancy tests

Melissa • 28 married to my childhood sweetheart ttc one more after all the mcs and ectopic pregnancies. fx
I just don't get it. I had a very light weird period which looked like ib almost two weeks ago. I'm constantly nauseated nipples r itchy constant headaches but keep getting bfn. I don't think pregnancy tests are as accurate as they say. I've been pregnant before and I feel pregnant now but every time I see a bfn all I wanna do is cry. I'm so emotional. Worse than before when we were ttc. This is really stressing me out. Any advice? Going for a blood test right now isn't an option
