Finding Your Fertile Window

Update May 1st 2026

Trying to figure out what day you’re ovulating on and trying to time your intimacy properly can feel really confusing. I hear this from my clients all the time and I think it has a lot to do with how little we’re taught about how our bodies truly work as women. I’ve worked with women for many years at many stages of their lives and it’s a common theme I see so please don’t blame yourself if finding your fertile days feels confusing. Add our modern world of LH strips, PdG, tracking apps and BBT to this and it’s a bit of a headache trying to understand it all.

But finding your fertile window can actually be easier than you think! Knowing which days are your most fertile is a crucial step on your TTC journey. For many women, once we get our periods, we’re taught how to prevent pregnancy. The conversation may go something like “you’re becoming a woman now and that means you can get pregnant” cue conversation about birth control. But the reality is, there’s only a few days a month where you actually have a chance of conceiving.

And if you don’t know how to find those few days (or you’re relying on an app to tell you), you can miss them completely and struggle with getting pregnant. But don’t be discouraged! Let’s cover some cycle basics every woman should know.

Menstrual Cycle Basics when you’re TTC

1. Follicular phase – your body is building the endometrium. The lining of your uterus where your future baby will grow. FSH is signalling to the follicles to begin to mature but the egg that will be released from the dominant follicle has been growing for the past 90 days! Which is why you need to give your body time to see cycle changes when you’re working to support your fertility 
2. Ovulation – the main event of your period! A surge in LH triggers the release of an egg. Estrogen will also peak. You may see thin, slippery, clear cervical mucus (like raw egg whites) and have a high libido, during this time. Some women also feel slight pelvic pain or cramping. The released egg lives for about 12–24 hours if it does not meet a sperm that fertilizes it. 
3. Luteal phase – happens after ovulation. Progesterone should rise during this time if you ovulate. It’s normal for you to begin to feel your energy start to decline.
4. Menstruation – some practitioners won’t consider this a “phase” of your cycle and they lump it into part of the follicular phase but having been in conversations with hundreds of women, we feel different during this time. Your body is literally shedding the endometrium. The thick lining it was building to prepare for pregnancy. It’s natural to have lower energy during this time.

In order to get pregnant you need to have an egg and a sperm that is already waiting for the egg which means it needs to be there BEFORE ovulation. To find out when you’re going to ovulate you want to get familiar with your body. Your body gives you signals and signs that ovulation is getting closer. 

Using Cervical Mucus Changes to predict ovulation

The most obvious sign your body gives you is a change in cervical mucus. This natural discharge you experience changes over the course of your cycle. Your mucus will begin to get thinner and there will be a lot more of it. In the few days before ovulation including the day of ovulation it may resemble raw egg whites – very wet, slippery, clear and stretchy. This is fertile cervical mucus – it means ovulation is very near and actually helps the sperm reach the egg!

You can also use LH testing strips to help you find this timeframe especially if you’re not really seeing changes in your cervical mucus. And the only way to confirm ovulation aside from getting a blood test from your doctor 7 days after suspected ovulation is to use a tracking method called Basal Body Temperature tracking.

I break down how to use this method along with LH strips inside the FREE Finding Your Fertile Window Guide:
