I had a positive OPK with first pee of the day and also a rise in my BBT on the same day.
Does that mean I'm ovulating today or was it some time yesterday afternoon or night since my temperature rose?

Positive OPK the same day as ovulation

My chart shows that I ovulated the same day as my positive OPK. I thought ovulation happened the day after a positive OPK. Is it possible to ovulate the same day as getting a positive OPK?

When you are using ovulation prediction kits (or devices that measure luteinizing hormone), you can usually expect ovulation to occur the day after your first positive result. This is because (LH) luteinizing hormone, the hormone measured by OPKs and the hormone responsible for triggering the rupture of the ovarian sac, typically surges the day before ovulation. In some cases, however, you will see ovulation on the same day as the positive result. There are a few factors that can help explain how this happens.

First, remember that when you are reading your OPK, you are seeing a snapshot of your LH surge. You do not really know whether you are seeing the beginning, peak or trail of the surge. What you know is that your LH is at a level that is detectable as a surge by the kit. It may have started to surge soon after your test the previous day and be starting to trail, or it may be just starting to surge. In a case where it looks on the chart as if ovulation occurred the same day as the surge, here is what may have happened:

1. LH started to surge during the night or early in the morning and was detected by your OPK in the early afternoon.

2. Ovulation occurred sometime in the evening or night, several hours after your positive OPK, possibly several hours longer than when the LH actually started to surge.

3. Your temperature is up in the morning, indicating ovulation for the previous day, the same day as the positive OPK, even though many hours have elapsed between the LH surge and your temperature rise.

Also, it appears that you are not using a basal body thermometer. Also your thermometer appears to be favoring temps. It's not usual that your temps would be so flat. You might want to switch to a Mabis thermometer.

Why am I getting "flat" basal body temperatures?

If your BBT seems to be around the same level all the time, the culprit is usually your thermometer. Even when you are taking your temperature at the same time and following all the guidelines, there is usually some fluctuation in temperatures. Your first step is to check your thermometer's battery or get a new thermometer. If your basal body temperatures are still flat, and/or show no sign of a biphasic (ovulatory) pattern when you would expect them to, this is something to ask your doctor about if it happens for a few cycles.

Thanks for the information. I thought there might be something wrong with my thermometer too, but I had my husband use it right after to just to see and it went to a higher temp when he used it. Also, I know this may sound a little unusual, but I went to the doctor a few hours later and they checked my temp and it was the same then too.

I would continue to HIO until you get crosshairs. Not only is it possible to have multiple LH surges in a cycle, but you could ovulate up to 48 hours after a surge so your temperature might have spike today and dip tomorrow.

That's super weird. But id still get one that goes to the hundredth. The Mabis is like $8. It's pretty unlikely to have the same temp everyday.

I have the iProven which has better ratings than the Mabis on Amazon. I agree it's weird. I took my temp and it was the same after three days so I handed it to my husband and he took his temp and his was half a degree warmer than me within a few seconds. That's why I don't think it's the thermometer.

I'm not sure what all acupuncture would do to your temp if anything, but fwiw I am getting acupuncture as well this month.

I get what you are saying, but your thermometer can "favor" temps even though it doesn't give the same temp every single time. Your chart is pretty obviously flat. and it's not normal to look like that.

Also, I don't think anyone mentioned this, but you aren't supposed to use FMU for OPKs. Technically your FMU contains urine from the day before (unless you also peed in the middle of the night), so the positive could be because of hormone levels from the night before.
