Are my lines getting lighter?

I’m so worried. I found out I’m pregnant and I’ve been testing non stop. I also went to get bloodwork done twice already but i don’t get my results until Monday. I haven’t been cramping and I don’t really have any symptoms but I feel like today’s line should be darker than yesterday’s. Should I be worried? I’ve had miscarriages before and i don’t want to lose this baby. 😔😭
