Is spotting during 4th-5th week is really normal?

Hi all. I'm currently at my 4th - 5th week of pregnancy and experiencing light brown spotting and mild cramp like those you had during menses. I consulted a doctor about other unrelated matters, doc advise spotting and cramp is not normal in an early pregnancy. Is it?? #1stimemom #pregnancy #advicepls #firstbaby #pleasehelp #bantusharing
