24 weeks bleeding

Ashley
I had heavy red bleeding yesterday. In panic I went to the hospital and found out that I have a low laying placenta which is covering part of my cervix. The bleeding stopped just before being released was told to take it easy and I'm to early to do anything about it . I raise a major concern concidering I'm already high risk. The baby was healthy and they said no cause for concern. Today the blood is old coming out dark brown color, I also passed a blood clot as well, had anyone else going thru this or been thu this and everything was ok? I read so many bad things can happen such as death to me and the baby. Kinda really freaks me out. If anyone can give any advice I would love it.
