I took a test yesterday morning and I could see a faint line and then I started bleeding so I thought it must have been a chemical. I thought I'd test again this morning just to be sure and I feel like the line looks slightly darker. You really can't tell on these pictures but I seen a faint line come up straight away this morning. I know it's probably a chemical but has anyone ever had this?

Yesterday's (top) and today's test - they look a lot clearer in person 😞 today's test was also second mu.
