I need help asap

So I’m a little confused. I’m not sure if your supposed to pull apart the digital but I did. So digital said not pregnant but when I pulled them apart they had a second line. The last one is super faint but it’s there but when I looked the line wasn’t there but when I came back to check on it cuz I feel asleep for two hours it was there. And there getting darker but they don’t pop up right away. I have an 8th month old daughter the pink one I took a day before i found out was pregnant with her I didn’t see anything but I looked 24 hours later and there was a line and now she’s here so I’m confused has anyone else have this happen?
