Basal Body Temp

Hi Everyone, My husband and I have been TTC our second baby for awhile now. I started basal body temping to track my ovulation, since my cycles are not exactly the same each month. One thing I noticed is that in the first part of my cycle my temps are extremely low- like between 96.7-96.8 degrees and then after ovulation they shift up but they only get to about 97.2-97.4 maximum. I definitely have the biphasic shift but my temperatures are low for each phase. Could the signify a problem? Does anyone have any insights about this? Help is appreciated!
