When Am I Most Fertile?

Getting pregnant is never as straightforward as you might want it to be. Even if you don’t have any diagnosable condition that could limit your fertility, you might find it takes longer than you imagined to conceive, and if you have a condition like PCOS that can limit your chances to get pregnant then you need to take specific action to redress the balance.

Identifying when you’re at your most fertile could be the key you need to getting pregnant, but there are two answers to this question: when in your life are you most fertile, and when in each menstrual cycle your fertility peaks.

In age terms, you are at your most fertile in your 20s to mid-30s. After the age of 35 your chances of getting pregnant ‘spontaneously’ (i.e., simply through regular, unprotected sex) begin to fall away. Unfortunately your life circumstances don’t always mean the best time to get pregnant is the best time to actually start a family. Fortunately, you can boost your chances by identifying when you are at your most fertile in each menstrual cycle. Concentrating your attempts to conceive on this ‘fertile window’ could give you the edge you need get pregnant when it’s right for you.

According to the NHS, you could get pregnant at any time in your cycle, especially if your cycles are naturally quite short – and they can be as short as 21 days. You stand your best chance, though, in the few days surrounding when you ovulate. Ovulation is the period when your ovaries release a mature, fertile egg into your fallopian tubes. It’s active for up to 24 hours, so if it encounters fertile sperm in this time, it has the chance of being fertilised and beginning the slow development into a foetus and then a baby.

Detecting ovulation isn’t always easy. Some people use hormone predictor kits, though these have limited predictive power if your hormones are off the baseline the kits are developed for. This can cause false positives and false negatives and makes it difficult to recommend them. Others check the changes in their cervical mucus – as ovulation approaches it changes in character to allow sperm access through the cervix and into the uterus and fallopian tubes. The changes you are looking for are quite subjective however, and don’t always manifest in the same way for every woman.

Basal Body Temperature is a more accurate method for determining ovulation. Detecting the pattern of small changes in your resting core temperature can give you an accurate indication of when you’re due to ovulate. OvuSense’s specialised sensor gets you the best results, and turns them into a prediction of when you’re due to ovulate with a unique algorithm, to give you the best chance at getting pregnant!
