Could I be miscarrying? My pregnancy was unplanned i'm 7 weeks.

On monday(today is thursday)i woke up and felt strong cramps and lower back pain. Later that day I experienced a flush of discharge. It was brownish/reddish with red little clots in it. Then when I went to the bathroom I noticed bright red blood and little clumps on the tp. Then tuesday I noticed brownish reddish discharge once not heavy at all. Wednes the same thing happened. Now today I went to the bathroom and I was pushing I felt pressure. But haven't experienced anything discharge except when I went to the bathroom and the discharge was clearbrown with dark brown spots. Sometimes throughout the day I feel like something is pulling at my ovaries from the inside and I feel pressure in the lower abdomen a vagina. Now all the pregnancy are gone.
