9 weeks and bleeding

Ma

So im bleeding again. It stopped for a few days but now im bleeding again. I also lost another 2 lbs that will be a total of 8 lbs lost this pregnancy so far. I am also cramping. The blood is again bright red and a lot. I didnt have any sex, I wasnt moving too much, and Ive been eating food a lot so I really hope my baby is alright. Any opinions as to why I started bleeding again would help a lot and thank you.
