Should I go to the doctor?

So I’m 10 days late on my period. On 8 days late I had light pink blood when I wiped. It lasted all of 6 hours and never got heavy. Light cramping. And my boobs were super sore. On day 9 of being late my mouth started tasting like metal. And I have A LOT of gas. Lol but I’ve taken at minimum 10 pregnancy test in the morning and throughout the day. They’re all negative. But like idk what else to do. I just don’t wanna waste money going to the doctor if it’s not necessary yet.

Update: I called the doctor and they told me it was too soon to tell on a home test. Idk. They think I need to give it 7-10 more days. But this dizziness y’all, it doesn’t make sense. I don’t like it.
