Ovulation predictor methods are many, and need not be expensive or complex for anyone with a regular cycle
Considering the last 14 days of a menstrual cycle is fixed in most women , ovulation will occur on day 14 in a 28 day cycle and day 18 in a 32 day cycle. Great if you one of the lucky ones who has a very regular cycle, that is the same length each month.
For the rest of us with more erratic cycles the reliable prediction of the timing for ovulation gets a little more complex, so here is a breakdown of the common methods of ovulation prediction:
Cervical mucous becomes more stringy and will form ribons when opposed fingers are extended. This method is great until you have had sex in the preceeding 24 hrs and mix sperm into the equation !
BBT or basal body temperature measurment, basically get an accurate thermometer are record your temperature at a set time every morning before doing anything else. Detects a rise of 0.3 degrees centigrade at ovulation. Contrary to popular misconception you do not need a 4 decimel place thermometer and it does not have to be farenheit. What you do need is a regular regime and set waking time, so its out of the question for shift workers or the less well organised of you out there who’s days wont give up the 2 minutes you have to lie in bed with a stick in your mouth.
Urine ovulation predictors. Dip test you dip in wee and tell you when you have a surge in the hormone which makes you ovulate. Expect to use 7-10 per month especially if you are irregular or have a long cycle. Buy dip ovulation test strips as they are just as accurate as digital or mid stream test and a lot cheaperas well as being more eco-friendly (less packaging) . Only go for the very low level, higher sensitivity ovulation tests if you do not get positive results with the standard sensitivity tests. Stick with a brand if it works (there are multiple sensivities on sale and comparing results is not possible) These tests give 24-36 hrs advance notice of ovulation.
Ovulation predictor miscroscopes are simple mini microscopes which show the crystal of salt which form in drying saliva when oestrogen levels are high which occur with ovulation. Can be used time and time again, so are cheap & eco-friendly if you end up testing for a long time. Look for models with replacable batteries. Don’t expect to see anything for the rest of the cycle, it takes 2-3 cycles to get confident in using these, so best to start off using while also using another method. They are 99% accurate when combined with BBT. Can also be used in dogs and cats, so popular with pet breaders, no reason why they could not be used in pigs, horses and cattle for insemination assessment, so come on you farmers !
Ovulation predictor didn’t work ~ Don’t panic 99% is just that, but not every cycle is ovulatory either, so re-try next month. If you get no positive indicators over 3 consecutive cycles change to another method or seek advice from your doctor. Up to 1 in 4 cycles can miss ovulation, and this increases with age and is a normal physiological finding.
