I'm 18 years old, and for the past few months I have had irregular bleeding to the extreme. Most of the time I can't keep track of my periods because they fluctuate so much. Most of the time I will either spot or bleed a brownish blood for two weeks then start my period which usually lasts about a week. Then I finish my period and sometimes I have about a week of normality with no bleeding before the brownish blood comes back until my next period! Let's just say that that week of no bleeding is like a grace period. I am absolutely miserable! I've made an ObGyn appt but it won't be for a few months. :'( I'm on my period now and this morning I had a blood clot the size of my fist! I know blood clots are normal in a period but I've never had one this big and it sort of scared me. I can't wait to get on birth control so all of this will go away!
