One of the best things I ever did as a woman is start tracking my fertility. What does that mean exactly? Well for one it is keeping track of when your period happens, but it can be sooo much more than that. If you are trying to conceive, there are tons of things you could be looking for to improve your chances. Also, tracking can help you to realize if something is wrong with your menstrual cycle.
I've found the best online tracker for me is fertilityfriend.com. I track pretty much everything, and it keeps it all in one neat place for me. I have the VIP version, as I need some of the more advanced stuff due to some infertility issues, but the basic is suitable for someone just trying to know more about how their body works. They also have courses for you to learn how to chart. Once you do it for a little bit, it becomes really simple. Honestly I was surprised by how much our body tells us, and how it tells us.
I really found it all empowering, and I hope you do too.
On a side note, if anyone would like me to send them an email invite for the website, it would be helpful. Each invite accepted gets me a few days of vip service added on to my account, and for each person who purchases the vip I get 30 days, as do you. :-)
