Perplexed over my condition

[morningtide]

I wake up in the morning with perfect basal temperature at 97.9F, but I have low blood pressure in the low 100's. I sleep ok although not every day of the week, but I don't feel tired in the morning. It usually starts around mid afternoon and then at 8pm. During the day I check my numbers again 2, 3 x and it's the same thing my temperature is around 98.3- 98.6, 7, and my blood pressure in the low 100's, sometimes a bit lower. I have taken the blood pressure trick where I take it sitting and standing and it is higher standing, so I don't think I have adrenal fatigue. So what is wrong with me? I try to drink a lot salt water which helps, but otherwise I just can't get my blood pressure up to normal. Thanks
