Question?

Okay, so the 23rd and 24th I woke up nauseous and ended up throwing up both times then yesterday I was still nauseous a little bit but I never threw up and then today I started my period like 6 days early.

I also took a test 2 days ago and it came out negative.

But is there any way it could’ve been wrong and I’m pregnant? Because my mother bled while she was pregnant with me and I don’t know why else I’d wake up throwing up and not throw anymore the rest of the day.

Also, I don’t think I’m sick because no one else is getting sick in my house.
