Can having a cold cause lower BBT?

eliana

Hi everyone, I had an <a href="https://glowing.com/glow-fertility-program">IVF</a> transfer on Friday and developed a cold almost immediately after the transfer so Ive been coughing. Today I would be 9 days post ovulation but my BBT in the morning seems to be lower than usual (98.16) today and wondering if possibly breathing through my mouth and having a cold could lower it? Thank you for taking time to read this! Feeling very anxious as this is my last embryo and last two transfers didn't work.
