I didn't know that I was pregnant. And the last week of November I had a heavy period where I was passing some decent sized blood clots in the shower. I have felt like throwing up and my breast are swollen and tender.. I took a test 2 days ago and it said that I was 1-2 weeks pregnant. Could I have had a miscarriage? I have an appointment on the 12th but I am curious to know sooner than my appointment... Thank you.
