Passed some clumps of tissue just this morning. Is this miscarriage?

8 wks pregnant po ako. Nung umihi ako kaninang madaling araw, I noticed na may tissues o blood clot sa t.bowl. Manipis na man siya. Parang half an inch siguro yung isa. Light red-reddish brown po yung color. Nagbleed ako pero kaunti lang naman. Worried lang po ako. What should I do? Wala naman akong ibang symptoms such as cramps. Masakit lang likod ko at pagooooood na pagod ako. #1stimemom #advicepls
