PLEASE HELP.

I'm starting to think something is terribly wrong with me, but I don't want to go to the hospital unless there is something wrong. I've been spotting for 19 days. it started very light and pink and the last few days it's started getting heavier. And today is so far the heaviest. I've had 4 full tampons and just a few minutes ago I stood up to get a drink and noticed That I started spotting again (I hadn't for a few hours) and when I went to the bathroom I had a few clots in the toilet and this larger one in my underwear. other than that I've had sore breasts and medium cramping today. I guess my question is, could I be misscarrying?
