Hi Kat,
Are you currently trying to conceive? I'm just curious as to why/how you know when you ovulated? I know at 19 I had absolutely no clue when I ovulated.
It was only later after we started trying to conceive that I started charting, tracking my symptoms and basal body temperature, that I was able to figure out when I typically ovulated.
If you are not trying to conceive, are you using any type of birth control? Since you are sexually active, I would definitely try to get on something asap. There are so many options today, that you should be able to find something that works for you. Also condoms are a good choice and you can usually get them free at a Planned Parenthood or similar clinic if money is a problem.
Let us know what you find out.
Take Care,
Autumn 32 w/CF
