Really need your help ladies!!!

I got a positive pregnancy test at 11 dpo, and then that night I had brown Discharge and really bad cramping all that night to point of it kept me awake. I tested the day after and it was really faint so thought I was have a chemical again. That day I started bleeding and bleed for about 5 days I tested again about 2 days ago and it was negative. I came off about 3 days ago but I’m still feeling sick and my boobs have started hurting again, so I did a test this morning and now there’s a faint line! Does anyone know what it could be? Please help😩😩
