Hi! I am currently on cd23 at 11 or 12dpo I think. And I was just wondering does your temp drop during implantation? My normal temp is around 97.5-97.9 but recently had went up to 98.8 and today it is at 97.4. I woke up feeling really nauseated and a few light cramps. Could this be implantation? TIA :)
