27 DPO and line looks a little lighter

Need your thoughts. My lines have gotten darker and darker and my hcg level was 14,892 on Saturday (this was my fourth blood check and it’s been great) this morning I took a hpt (my way of comforting myself the baby is there) and the line was a little lighter than the past few weeks. I did get up to pee 2 times during the night 12am and 2:30am) so I tested it with my third morning pee (5:30am) should I be worried ?? No bleeding no cramps nothing please tell me
