cramping and bleeding.......

Okay nothing to do with me but my best friend. She found out she was pregnant confirmed by hpt and also health department did a test and was also positive. But here past couple days she has been having cramping which I know is normal in early pregnancy but also has been having a brownish color bleeding(spotting) she hasn't done anything unusual all her normal daily things. She is only about 6weeks maybe little more in pregnancy... has anyone or is anyone going thru this and everything is okay??
