First natural period in 13 years!

I've always had problems getting my cycle and haven't actually had a natural one since I was 15. I was on provera and clomid this month - same when I conceived my first child a couple years ago. I was starting to feel pregnancy symptoms, but ended up just being AF. I actually got a natural period today! I'm in shock! I'm weirdly thrilled since I know my body is actually starting to work right. I know AF is obviously a sign of no pregnancy, but am so thankful I actually have a period this month, not caused by meds!
