Scared to test

Been nauseous to the part i have to run to the bathroom. Sometimes i throw up other times i don't. Even water makes me nauseous. Been having lower back ache and fatigue and been going on more trips to the bathroom especially at night. Have cravings and been moody yesterday i was in a bad mood today i been crying. Something inside me tells me I'm pregnant. I'm just scared to test. I'm afraid to see a bfn! I had unprotected sex January and last month. My last period wasn't normal short and light i wanted to wait until i got my period but i was going to test tomorrow because my chances of miscarriages and if i am i want to know sooner to take care. Did any of you had that feeling you were pregnant and got a bfp?
