I Am Bleeding And I Think I’m Pregnant But I

I am bleeding and I think I’m pregnant but I haven’t had the time to take a test to find out and I was wondering if I could possibly be having a misscarage. I stopped my birth control and my last period started on August 27th and I haven’t gotten in sense but I have had pregnancy symptoms and was going to buy a test today but I just started bleeding and I don’t know what it is or if I should still take a test
