IM SCARED... PLEASE HELP AND READ... IS MY PERIOD SUPPOSED TO DO THIS? CLOTS AND ETC.

Every time I have my period, it is usually long for about practically a month. And when I don't have my period (which is not often) it only last about 3 days. Is my period supposed to last this long? And occasionally, but not recently, I experienced blood clotting and the toilet bowl would be filled with blood and begin pouring out like lemonade in a pitcher. The blood clots are very dark red, and like a bunch of blood worms of jelly (or like how others have described blood clotting). Does this have anything to do with me being sexually active? And just recently, I was sexually active and now I might be pregnant, but I am not exactly sure yet. I don't want to have this baby, but I will be taking a home pregnancy test soon. What can I do about this blood clotting? And what about having my period for so long and frequent? And what are some signs of pregnancy and what can I do about it? I'm fairly young, and the blood clotting didn't start until last year. And I really really don't want to be pregnant right now... Tweet
