Is my test correct ?!?

Hello all ,

I am a mother of an almost two year old . And we really haven’t been trying to get pregnant but have been throwing around the idea. For the last couple weeks I’ve been having cravings like I did when I was first pregnant. I’m more wore out than before and unable to sleep . Been having hip and back pain out of no where . I noticed yesterday that I was bloated up and thought it was just my incoming period. Upon waking up with our child at 12 am . My mind was racing so I took a test , I waited the a lotted time and it seemed negative. I happen to go back after a hour or two and there was a second line but faint . Do I need to rest test or just wait and see if I’m going to have a period .
