A feeling...?

Did anyone just have a feeling they were pregnant and actually were? I haven’t tested yet bc I don’t want to get my hopes up or test too soon bc I’m only 13 DPO but I just have a feeling I’m pregnant. I’m getting nauseous during meals, itchy nipples, throbbing breasts, cramping, headaches, mood swings, I just have a gut feeling but I’m afraid to get my hopes up and test
