Ttc number 2

My af finished on the 12th of this month, also the day i had my implant removed. Have had sex at least 3 to 4 times since then. Started feeling extreamly bloated, gassy, not cramping as such more like belly ache, nauseous. Exactly as i felt when pregnant at first last time. My af is apparently due in 8 days. But when i was on the implant my af was around once every two months of so. Ive done a few tests but all negative. Am i just testing to early? I got a positive 9 days before af last time.
