TTC - Doubt. Tomorrow morning (9dpo) ?

Hi Doc, I'm currently completing 8dpo (writing this mail at night). Post ovulation I had a creamy lotion type white discharge. And now I have a thin, white and stretchy discharge. Also, intermittent mild cramps, lower back pain, slight throat pain, heartburn, bloating, gassy, tingling sensation in nipples along with little pain when touched, muscle aches, fatigue and intermittent headaches. I felt nauseous twice at 6&7dpo and the aforementioned symptoms. I never had these symptoms before menstruation. Since we are TTC, I'm eagerly praying to hear a positive result. I took a test tonight (8dpo) out of curiosity and came out negative. Please help understand what's happening. Am I pregnant? Shall I take a test tomorrow morning (9dpo)? Please help me. Thank you a ton in advance.
