Spotting and cramping


So I believe I’m around 4 or 5 weeks.. I go to the doctor this week. Since Thursday night I have been spotting- sometimes pink, sometimes red, sometimes brown. I’ve also had some cramping- varies in intensity. The spotting has never been that heavy. Doesn’t fill up a pantyliner and when it drops into the toilet it’s just a couple drops. Is this normal? I’m making myself crazy googling stuff. This is more stressful then I thought it would be after several positive pregnancy tests 🤦🏻‍♀️🤷🏻‍♀️
