I have thought really hard about this today and i am thinking about possibly getting her put on the pill that will stop her from having them at least until she matures a little more.
I am SO glad you've decided not to do that. Next time ANY BC pill ad comes on TV, listen to the risks that they state, out loud, in an advertisement FOR the product. Extrinsic hormones are terrifying and have nasty risks. Not to be given lightly, and as you've come to realize, this is NOT an issue at all.
I would absolutely not put my child on medicine to change something that is perfectly natural. Kids as young as 8 start their period. I got mine when I was 10 or 11. Sucked, but I just would try and treat it as special thing that girls achieve. That is what my mom did. We had a special day out and we spent some time together. Heck, I was wearing a regular bra in fourth grade. By fifth, I had started my period.
I should have been wearing a bra about a year before I started my cycle. And after the first (aka "menarche") I didn't have another for a year. I was on the young side for my grade, and was one of the last to get it, probably in 5th/6th grade.
A 10 year old girl is capable of understanding how her body works and at the same time maintaining her innocence, playing with dolls, etc.
Absolutely.
There are also real risks to being on the pill. I know everyone thinks it is harmless, but I was one of the "unlucky" people to get a blood clot from the pill (as an adult). There was no warning and I did not have any of the known risk factors. I had a serious bout of ischemic colitis from the blood clot. I was actually lucky I did not get a stroke or heart attack instead!

Glad you're OK.
I just meant i didn't go into detail about ovaries & eggs and that kind of stuff.
Why on earth not? It's her body, and the more info she has, the more informed she'll be and the better care she can take care of herself.
Listen, I knew some, because my mom shared stuff with me. But then I was such a shy and easily embarrassed girl, I started ignoring her. Then I found myself in my mid-20s, being naughty, and thinking that one body sign meant that ovulation was OVER, so I was "safe".
Then I met my husband and we knew we'd want to try for babies soon after getting married, and I picked up Taking Charge of Your Fertility, and found out that the sign I thought meant it was OVER actually meant "you are the most fertile you are going to be this month". OMG.
You've got to get your daughter the info about her body so she doesn't do stupid things when she's older.
As my *son* grows into a young man, I'll be teaching him about his body (my poor husband was taught nothing, and was entirely freaked out about things that happened with his body until he was around 16) AND about women's bodies, because I've known waaaaaaaay too many woman who knew nothing or lied to their unknowledgable boyfriends about what was "safe" when (so they could get pg)...I think it's important for humans to know how humans work.
