Hello, I am 26 years old and my period was 6 days late. I have always been on time with my periods . I finally started bleeding on the 7th day. It was light for the first 4 days and now it is heavier with tiny blood clots. Every once and awhile I get a cramp or 2. I took a pregnancy test but I couldn't tell the results for sure. It looked negative, but I THOUGHT I could see the 2nd line appearing. I don't know for sure. Could I be pregnant and having a miscarriage?"
