I just found out I am pregnant, an ultrasound , urine test, and blood work confirmed it. I am 6 weeks and 3 days, and I have some concerns about experiencing light bleeding two or three times last night. It hasn t been heavy, but I do believe there was a clot in it. It was dark purple and not big at all, maybe the size of a raisin. Any idea what this was, or if I should be worried?
