Temperature

Michelle🐶 • 8 angel babies, now divorced but still hopeful for my first human child - already have my pitbull fur baby!!
Will your BBT always stay elevayed if prwgnant? I took an OPK and had a peak reading but my temp only went up .02. It's been staying in the same range all week and I would have ovulated fri or sat. Could I still have ovulated or does that indicate an egg didn't drop?
