Advice needed..

Hello! I have a 32 day cycle and I'm on cycle day 24. I ovulated on cycle day 18 so today is 6dpo. We are ttc and have made sure to be intimate when i was ovulating and before ovulation etc.. The last 2 days I've had lots of creamy CM, back acne, constant hunger yet a bit nauseaed, moody and headaches and extreme fatigue. If AF is due onMarch 15th, when should I test? Is it too early to be experiencing pregnancy symptoms?! ☺️ are these just symptoms of af coming?
