It's possible that you have just sprained your foot.
You need to lift your ankle so that the leg is straight in front of you on a chair, use ice packs for 20 minutes each hours until bed time and you can apply Arnica montana cream on your foot or you can take tablets of this homeopatic remedy( it's helping with pain relief, swelling and bruising)
Can you visit your doctor and ask to be x-rayed?
Did you have heavy periods for the last two months?
Since when you have been anemic?
Do you take iron supplements for you anemia?
Life style and nutrition always affect woman's menstrual cycle.

I went to the Doctor after a night of little sleep he x-rayed my foot and said that it was a hard sprain which is better than broken but I will be on crutches for a few weeks he said. I am supposed to keep off of it cause if I apply pressure it could snap the bone and break where it is weak. My peiods were somewhat heavy for the first few days on the first one and by the forth day it lightened up. Then a week after I was off I started again this is really frustrating and confusing me. I only weigh 123 pounds and I am 5 9 1/2 so with that beeing said I am very small. I am not a big eater but I do eat. My hubby is always giving me heck! I give blood at blood drives probably 4 times a year which my hubby does not like but I figure I can save lives and do my part. I can't take supplememt because it messes up my body. I have stomach cramps and get really nautious and sometimes even throw up. I can however take flinstone vitamins with extra iron which was a recomendation. Thanks for your thoughts and input it helps put me at ease a little more.

As I understand from your post, you had experienced menstrual bleeding twice in a month. Is this happening for the first time?
For how long you've been anemic?
You can try to improve your blood by eating iron-rich food( chicken, turkey and beef meat, spinach, dried apricots, dried peaches,prunes, raisins)
