Confused, can anyone help?


So my fiancé and I have been trying to get pregnant for 6 months now. I know it’s not a long time, but when AF keeps coming to town it’s very disappointing and hard. Well currently I’m 5 dpo and today I felt nauseous all day and have been having sore nipples, diarrhea, cramping, lower back aches since I woke up, and feeing dizzy/ lightheaded. Should i wait until I miss my whole period completely to test? Or should I wait until I’m 10-12 dpo?
