Help!?

Elaina

So I'm really late on my period almost a month but I really don't think I'm pregnant. I've had "scares" before but the result has always came out negative. So I don't feel like I need to take one. I'm also overweight trying to lose weight and it could be from that but idk if it is and I'm just scared to take a test cuz if it's negative I get real bad depression...
