As long as your temps are above the cover line then I wouldn't worry about high temps. It could be going triphasic, which is slightly more common in pregnancy charts, but also occur in non-pregnancy charts. We get a second oestrogen surge a few days after ovulation and as that tapers off your temp should rise as oestrogen keeps temps down. No symptoms isn't a worry either, technically you wouldn't even get symptoms till after implantation, which happens (usually) between 7dpo and 12dpo with 9dpo being the most common day (it has happened earlier and later for some women, but is by no means the norm). So you might not even have implanted yet, which would mean no symptoms yet. Even then, many women don't get symptoms till after their BFPs. Good luck this cycle, hope you get your BFP.
