Nervous... Very Early Pregnancy Question

Is this three day progression okay for being 3 weeks 6 days pregnant (I'm only 13 DPO today)?????? It's  been confirmed on a digital and many other tests, so I'm doing the cheap Walmart ones the next few weeks to make sure it gets darker... I feel like these Walmart ones have such lighter second lines than all of my other tests! I'm so nervous after having a miscarriage last December... I just want a healthy pregnancy! 💗
