Help !

Hey so I have brown discharge I think)but it lasted for about 7 days straight and there no more blood or anything like that just lots of small pain in my lower half (Like a lot of that pain) and it won’t stop. My stomach hurts I feel sick and my head hurts. Shouldnt it be gone by now?

I’m scared cause I went on google and it says stuff like pregnancy ,or infertility or cancer ! 😖 but the pain is my biggest concern is it normal when I don’t think I’m on my period no more?why wont it stop?
