7 dpo and sick to my stomach 🥴

My period is due next Monday but for the past 3 days I’ve felt so sick. Nipples sore, headaches and nausea started today. And now I this thick creamy white discharge. We’ve been ttc for 3 months now and the discharge doesn’t smell or look like yeast or bv. Is this normal possible pregnancy symptoms or is af just sending signs early.
