Depends how far along you are and if your temp drops below the cover line.
@Amy I’m 4w2d
From my knowledge temp is supposed to stay up at the beginning stages of pregnancy, though hopefully yours is just fluctuating slightly and will go back up. Temp isn’t always an indication of a viable (or non viable) pregnancy though, I had sustained high temperature and had a blighted ovum. Try not to read too much into it. Hope everything is ok
No doesn't mean that body temperature goes up and down all the time
