Q&A: What is basal body temperature?

We've been trying to get pregnant, and a friend of mine told me to take my basal temperature. What is that, and does it really help?

The Bump Expert

Tracking your basal body temperature (BBT) can help pinpoint your ovulation date, and thus the best time to have sex. Take your BBT with a basal thermometer (sold at drugstores) first thing in the morning, before you do anything. This gives the most accurate reading -- even a quick bathroom dash can raise your body's core temp. Keep the thermometer on your bedside table along with a notebook to keep a daily record.

In the first two weeks of your cycle, before ovulation, BBT averages between 97.2 and 97.6 degrees. A day or two after ovulation, your body temp spikes between half a degree and a degree, and remains elevated until your next cycle begins. Keep in mind that from day to day, your BBT can fluctuate by half a degree or more. Don't be fooled by a little blip -- look for a sustained rise to confirm that you've ovulated.

The downside of BBT is that it shows when ovulation is over, not imminent. Track it for several months, though, and the info will give a sense of when you usually ovulate... Now just plan your sex life accordingly!

Q&A: What is basal body temperature?

I take my BBT every morning at 5AM (I know, it's early, but at least I'm consistent!). I take it orally, though, and sometimes I move the thermometer around a bit before I'm satisfied with the position. This morning I had a lower temperature, and it beeped pretty soon after I had moved it. Could my temp be off because of moving it around in my mouth?

Yes, when you buy a thermometer and read the directions in the box, it tells you that your mouth has some heat pockets found on the sides under your tongue. That is where you need to place the tip of the thermometer. If you move it around you won't get an accurate reading. If you open your mouth while moving the thermometer around, you will loose heat.

Sorry to discount the Bump Expert, but I track my temp every day and have since Feb. (previously in an attempt to avoid pregnancy... which worked! :)). My BBT before ovulation is always between 96.0-96.8, some months higher than others, but always in the range. After ovulation, it spikes to between 97.2-97.6. I don't know if that makes me an oddball or not, but I just wanted to throw it out there that you won't necessarily be between the 97.2-97.6 prior to ovulation, as listed.

Do you have to take your temp. at the same time every day?

skin103414- Everyone has a different temp. so your not necessarily discounting the expert. my average temp is about 97.6 I used to have a heck of a time at school because if I had a 99.0 degree I had a serious fever. It would be like an average temp of 98.6 person having a 100.00 temp. I would never get sent home. haha. So dont worry your just a little "cooler" than the rest of us. LOL!

kayreejay: I found another article on the bump and it said "Body temperature will remain roughly half a degree higher until right before menstruation, when it will return to normal. (If you get pregnant, your temperature will stay higher through the first trimester). If your temperature doesn’t follow this pattern, it might indicate an ovulation problem."
