The best thing to do is go on the NHS website it tells you more information on there that helped me.

I used a few different apps as mine were irregular they seemed to help have a look in your app store read reviews and see what you feel confident with xx

Have you tried getting an app to track? I use My Days X to log temp/symptoms/cycles/cm etc & it predicts your ov date on your data that you've entered xx

That's great! Thanks for the advice ladies! @holmes & @missjox xx

there's loads of things you can do to tell when your ovulating too. I managed to fall pregnant first time just by watching out for the signs.
firstly you need to track your basal body temperature. check your temp every morning, it will be around 36dgc, then usually around 3 days before ovulation it will suddenly spike.
also check the height, softness and openness of your cervix every morning. when your getting ready to ovulate it will be high, soft and open. usually it will be low and hard.
also look at your discharge. when your body is ready it will go very clear (like egg white) and may have some blood in.
when you get all these your about to ovulate in a few days time! remember sperm takes about 3 days to reach the egg so having sex on the day of ovulation won't work as the egg would of died before the sperm gets there. and not too much sex either, it's takes a good 2 days to build up enough sperm to maximise your chances. most of it is just semen so you need to give your partner time to recover ;)
hope this helps and good luck! :) x

its about 14 days after you Period
