Should I test?

My period is due in 3 days and I’ve been feeling nauseous for a little under a week. I also have extremely sore nipples and my boyfriend says they seem darker but I don’t see it. I also have been extremely tired. I cry for no reason now too all the time. I had slight cramping a couple days ago that only lasted that day.

My boyfriend and I are new TTC as we have only been trying since April so anything advice would help.
