I started feel waves of sickness about 7 - 10 days after ovulating & wasn't sure at first if I was making up but I wasn't its got worse & worse each week & I'm defiantly PG - good luck to you ill keep my fingers ceoased
I had waves of slight nausea 1 week after this time but both pregnancies the most compelling first symptom ( before missed period) was hot flushes and feeling warm all the time, as well as a massive appetite and waking in the night.
I felt nauseous around 12 dpo for the first time, really dizzy as well. Yours is only 8dpo so around when I was having implantation spotting but you never know! I tested positive at 11dpo so you can probably test in a couple of days, good luck
