What is this?

My period is scheduled to be in 6 days, but they are irregular so it may of may not happen. I had sex with my boyfriend February 2nd and went on a trip February 7th. I came back on the 9th and took a test about a week later. Since then I haven’t been throwing up or nauseous and I haven’t been cramping or eating more than usual. Thing is, today I happened to be very horny and after some things this showed up and I don’t know what it is or what it means. I don’t know what to do. Any ideas?
