Ok. So Two Weeks Ago My Boyfriend Came In Me

Ok. So two weeks ago my boyfriend came in me a lot because our condom broke. I think I may be having a miscarriage. I starting having brown spotting then a lot of blood then brown spotting again and just now in the tub brownish red tissue (small amounts) came out of me and so did this weird white egg-like looking thing that wa clear in the water and I'm freakish out man. I'm a 17 year old vegetarian. Is it my age? My diet ? Other symptoms are a fever, abdomen pain, stuffy nose, fatigue, nipple tenderness and mood swings.
