i don’t know as much about it as some people on here. Maybe comment in one of the CHARTERS boards because they are always happy to give advice and share knowledge.


i keep track of my periods. So cycle day 1 (CD1) is the first day of my period. Then roughly CD12-14 is when I am most fertile. I write CD1 CD2 in my diary everyday.. Then once I get my next period it starts at CD1 again. After doing this for several months I could work out that my cycle lasts for 27 days (usually) so then I know when to be prepared for my period.     


i have charted in this way for a few years mainly just to keep track of when my periods are.  But last month we decided to try to conceive (TTC) so now I am trying to time our BD (sex) so we hopefully become pregnant.  


if you do a search online for ‘ovulation calculator’ you can put in the date of your last period, the length of your cycle and then it will calculate when you are most fertile and also when your next period will begin (approximately).


Good luck 🙂 it’s good fun. I have learnt so much about my body xx

nearlymarriedlass:  The best thing to do if you want to learn charting is to read Taking Charge of Your Fertility. That will give you a great explanation of all the things to take into account if you decide to start charting! Basically, you take your basal body temperature with a basal thermometer at the same time every day, just after waking up but before getting out of bed. You should see a pattern of lower temps before you ovulate and higher temps afterwards. After doing it for a few months, you might see a pattern – for example, I generally ovulated on cycle day 16, so I knew that sex on day 12 and 13 was not as likely to lead to pregnancy as sex on days 14 and 15. Some months, you will ovulate earlier or later, though, so using an ovulation predictor kit is a better way to tell when you’re about to ovulate. Charting will just confirm ovulation after the fact. Good luck!

nearlymarriedlass:  I’m one of those ladies who charted while not TTC to avoid pregnancy (for about a year before we were ready to try).  I think it seems complicated for some people at first, but it’s really not.  

What it involved for me was taking my temperature every morning (I just had a thermometer on my nightstand, and I’d pop it in my mouth right after my alarm went off), plugging those temperatures into an app so I could see my trends over time (most of us on here use Fertility Friend, but there are other apps that do it, too, like TCOYF), and checking my cervical fluids throughout the day when I used the bathroom.  The temperatures confirm when ovulation happened (after the fact), and the cervical fluid can help tell you when ovulation is approaching/when you’re most fertile (before the fact).

Some ladies do “chart” just using a calendar (that really is not what we’re talking about on here when we say “charting” – it’s what’s widely known as the rhythm method), but I would strongly disuade you from doing that if you’re trying to avoid pregnancy – all it takes is one month where you ovulate earlier or later than normal to get pregnant doing it that way.  Instead, using the symptothermal method (temperatures, cervical fluid, and your body’s other signs and symptoms) helps you know what’s going on with your body each individual month.

Phew, wasn’t planning to write a novel!  But I loved charting!  I did it for a year while trying to avoid, then used charting to pinpoint my ovulation and got pregnant our first month trying.  We’ll definitely be using it again after our baby is born.

ETA – just an additional note – ovulation calendars/predictors are OK for getting a general range of when you might ovulate, but they aren’t accurate for everyone.  They go by averages, and lots of women are not average!  For example, I had 28-30 day cycles, and most calculators would say I’d ovulate around CD14 or 15 – I never did.  I tended to ovulate later (averaging CD18, but as late as 23).  Charting is great in that it takes out the uncertainty – lots of women aim for that estimated ovulation date, not knowing for months that they aren’t having sex at the right time.  I would have been one of those ladies had I not charted.
