So lately I've decided to start tracking my cycles and periods as we may start TTC during the middle of next year. Hooray!
But I'm kind of unsure how to do this. It's sad, being a girl and knowing very little about my reproductive parts! Here's my question(s)and sorry if this is confusing I'm not really sure how to word this I guess:

In terms of fertility, how do I determine a general idea of when I ovulate and when I'm most fertile? It's easy to tell the first day and last day of my period, but I'm not sure about the rest. I want to be able to answer that common "how long is your cycle" question but I have no idea.

Now, I am currently on birth control, so I know I do not ovulate, but I want to get in the habit of doing these things NOW and knowing what to do before I stop taking it.

Once it gets to that point I plan on buying a thermometer and checking my BBT but I will look more into that when the time comes.

I'm just trying to keep myself occupied with making my body healthy and getting in the habit of things I'll need to do before/during pregnancy so it will make me feel a little less anxious!

Thanks in advance for any advice you can offer :)
