Positive test after period?


Anyone ever gotten a positive test just days after their period? It seemed like my period was a few days earlier and was really weird and watery this time. I decided to take a test because i was having pain on both sides of my hips and it's a positive, but not too dark. Is this possible or do i have a faulty test?! We've been trying forever and end in chemicals so im definitely not trying to get myself excited but i am a little!!!! eeep!
