Occasional light pink tinged discharge 4 weeks

Hey ladies, I’m very newly pregnant. I am only 4 weeks and 2 days. I have been having some occasional (off and on) light pink tinged discharge the last few days. It’s not every time I wipe, only some of the time , but it’s super light! I had an HCG blood test, and my levels are going up, but I’m still nervous with the spotting. Can anyone share their experience with this? How did it turn out for you?
