So I am 38, had my tubes tied 17 years ago. I normally have a heavy period every. 28 to 31 days. .The day my period was due was Dec 7. I had light pink discharge for about 2 or 3 hours. Then it stopped. 2 days later the Same thing happened for the next 2 days. Then it stopped. Took a pregnancy test and it was negative. Went to the emergency room on the 18th. They did a urine and blood test. They were both negative. I started what looked like a light period on the 24th. Pregnancy test still negative. On the 25th I started have large clots with the light bleeding. They are as big as strawberries. What is going on with me. I was wondering if the pregnancy test could be wrong?
