I lost my son! Should I hire a Malpractice Attorney?

I am writing this because I lost my son at 22wks. I had went to the hospital every week and then every other day. I was bleeding and had a blood clot released. 1st I was told I had an UTI and was given medication and sent home. After medicine was done I still was bleeding I went back to ER and I was told that sometime women just bleed. I kept going to the hospital telling them something was wrong they told me no go home and relax. US where done every time I went and I was told he is fine. Till one day I was admitted and I was in preterm labor. I had to deliver my boy and during delivery he came out sideway and he was all bruised and the Dr was pulling and tuging for him to come out. I did an autopsy of the baby and he was healthy but had marks on his body. I don't know why all this happen?
