I Had Constipation Today, And I Strained And Sat For

I had constipation today, and I strained and sat for about thirty minutes..then gave up and went andsat down to watch tv for a bit and drink something. In about an hour...I felt the need to go again, and I tried again with some straining. I finally had a bm and filled the toilet bowl with blood. I have a history of hemmoroids....do you think this is what happened to me?
