Is normal to bleed when you are in 4 week of pregnancy?..

Jennifer

Last night i went to pee and i saw blood on my panty liner and after making pee when i wipe my thing theres a blood again..its like a light red blood thats when i ask my husband to bring me to the hospital because im to scared to have a miscarriage again.. the doctor told me to wait for 2 more weeks to have a scan. Just wanna know if someone experience it too and is that normal?..
