is this normal? TMI

so I am 8 weeks pregnant almost 9 weeks. this morning I woke up and seen this? I wiped and seen this and had some in my under wear. 3-4 weeks ago maybe now I already had spotting but I didn't know it could keep doing it. it is 10:10 PM and it's been happening all day. not bad just light. and I know it's not a miscarriage because I have had one before. But is this normal for being 8 almost 9 weeks? If so, how long could it last during my pregnancy? thankyou.
