Pregnancy

Hey girls! I have a question... so I’m 18 and me and my boyfriend have a temporary long distance relationship. When ever he comes home we have sex , regardless of me being on my cycle. We ALWAYS use condoms because I’m not on the pill and I’m still in high school. Last time we had sex I was on my cycle and we used a condom , although they don’t always work. I can’t recall a true cycle last month and I’ve been spotting in random times. My hunger is super high and today after my coffee and bathroom break I got nauseous. My app says my next period should be next week and I’m not cramping like usual. Should I take a test now or wait til next week? I live with my parents and they don’t know about me having sex. But if I am pregnant I’m pretty excited. Any advice?
