Spotting all day. Positive pregnancy test on Sunday

Sophia
Hi all! I've been having pink spotting/discharge today. According to the apps, I am between 3 weeks 6 days to 4 weeks 5 days pregnant. I do have a picture of it (if needed). Has anyone ever experienced this? I'm having no cramping. I had slight cramping last night. My breasts aren't as tender as they were on Sunday. They can at least be touched now. I'm worried. This is my first pregnancy. TIA!
