What are the signs of being anaemic?

I've heard what some of the symptoms are, but i just want to know if there are others. I can sleep for a long period of time. I could easily get 11 or 12 hours of sleep. It's hard for me to wake up, even though i had all that sleep. I get dizzy once i wake up and get out of bed or am sitting down for a long period of time. I have a really heavy period, but it's very irregular. I'm also a runner and I heard many female runners have anaemia. I do not eat any red meat, rarely any meat at all. I feel very fatigued after running and usually take a 2-4 hour nap afterwards. I get shortness of breath just from walking. I also heard that getting blisters in your mouth could be a sign, is that true? I'd just like to know if these symptoms are true and if there are any others, thanks.
