Confused, please help!

I’ve been getting this since the 10th. Sometimes there’s nothing and other times there’s this. My period isn’t supposed so start until the 18th. I keep waiting for a period like flow to happen but it just doesn’t. I also took a test on Friday and I kind of see something, but I took a pink dye also and didn’t see anything. I’m just wondering if something is wrong with me or if this is normal and if this happens to anyone else too? Please lmk!
