please send prayers

My period is supposed to come on today, but it hasn't. I haven't felt cramping but once and my breast aren't super sore like usual. For the past week I have been having this nausea feeling around night time. I feel like I need to throw up and will feel better if I do. But nothing ever comes. I'm so scared to take a test and it be negative. Has anyone else had these symptoms before and pregnant. Prayers and baby dust to everyone 💕
