Is this normal?

I’m not 100% sure how far along I am because I have long cycles. I think I’m between 4-6 weeks. I’ve been spotting for almost a week. It hasn’t gotten worse, some days it’s barley there but still there. I’ve had some light cramping but again, they haven’t progressed. It’s more of discomfort than cramping.

I won’t see my ob until 1/22 for my first check up. I’ve taken more pregnancy test and they’re all still strong positives. It’s my first pregnancy. Should I be worried or no?? Has anyone else had this in early pregnancy?

The spotting is always brown with maybe a small, small hint of pink and the cramps usually happen when I’m moving (if I’m sitting then get up etc..).

I’m worried if loosing this baby because I’ve wanted it so bad and it’s taken me a while to bet here. Can someone please assure me that I’m okay and the baby is okay!? Should I call my ob and tell them I’ve been bleeding for almost a week!?
