So ive tested 3 times now with first response 6 days sooner with the curve handle. Tested at 8 dpo, 13 and 16 dpo. All negative. Af was supposed to arrive Thursday. And still nothing. My cervix is high today could barely touch, and it was low just earlier this week. Cramps and bad nausea come and go since for almost a week now. I know pink dye is the best but i wonder if i should go with a different brand? Im never late and they deff do not feel like af cramps. What do ya'll think?
