Worried about body temperature

Guys should I go to a doctor my temperature been 90.0 yesterday and now is at 91.2 exactly . This is driving me nuts . I am not sick and I take vitamins daily I am currently TTC . The normal temperature for a human is 98.0 or 97.5 and I am taking my temperature in Fahrenheit. By the way this is not my basal body temperature I took it this morning and is at 100.1 but I am cold as hell on the outside apparently . And just yesterday my basal temperature was at 106.1 . What can I doo ?
