Lighter test? Should I be worried?

My husband and I have been TTC for 9 months. I was diagnosed with PCOS but considered in the normal range of hormones at the beginning of trying. I got my first BFPs on Thursday and decided to test again Friday and Saturday. I know that HPTs (especially the internet cheapies) aren’t accurate to measure HOW pregnant, just yes or no. But I’m kind of worried that the lines haven’t gotten darker. Should I be worried or just wait to get my blood tests done in a couple of days? This is my first and I’m so nervous considering the risk with PCOS😱😫
