I want pretzels and cheese -_-

is it normal to have bruising tits?

I really need help. I think I'm pregnant but I'm too scared to get a test but last week I was supposed to have my period and all it was was spotting of like dark brown something...I don't want to freak out my boyfriend and tell him I need a test but I just feel like somethings not right. I'm always thirsty and tired. My appetite varies and I haven't slept well in a couple days...someone just tell me...do I need to test?
