Did you know irregular or abnormal ovulation accounts for 30% to 40% of all cases of infertility? The absence of periods, abnormal bleeding and frequent irregularity is a major indicator that you are not actually ovulating – known medically as ‘anovulation’.
If you experience anovulation it’s important to consult with your GP to eliminate any conditions that may be interfering with you ovulation such as thyroid issues or abnormalities of both the adrenal or pituitary glands, before starting your fertility journey.
If your periods are irregular, pinpointing your ovulation can prove difficult. For women who have a regular 28 day cycle and taking into consideration her ovulation and the lifespan of the male sperm, it’s safe to estimate that she is more likely to fall pregnant if she has sex between day 8 and day 18 of her cycle. Having sex during the first 8 days or the last 10 days of her cycle, means she is unlikely to successfully conceive. However, this is not an exact science and can lead to disappointment or an unplanned pregnancy. Try our Ovulation Calculator for help in determining your ovulation and ‘fertility window’.
Irregular periods make using a ‘safe period’ method of contraception extremely unreliable, ovulations monitors such as the Persona monitor can be used dually, either as a fertility aid or contraception guide, detailing the days when you are at your most fertile and conversely when you are not. Remember the main principle behind using the ‘safe period’ or ‘rhythm’ method of contraception is, in order for it to be effective, the woman using it, needs regularity in her menstrual cycle.
Couples who are trying-to-conceive and may be experiencing difficulties may be advised to keep a temperature chart by using a Basal thermometer, or to use an Ovulation Predictor Kit. The body temperature increases slightly (around 0.2°C) after ovulation, so charting your temp over the course of a few months can indicate when and if ovulation is occurring. Ovulation Predictor Kits can measure the levels of key fertility hormones in the urine and indicate when ovulation takes place.
