i had unprotect sex right after i ended my period a month ago. i started getting quite a few symptoms of possibly being pregnant but i didn't think anything of it until i noticed some blood on my toilet paper (i thought i was spotting). i was a couple days late, but, i just started my period today and it's very different than usual. it's not as heavy and when i pee'd there was a large redish transparent discharge. it was like a chunk of body tissue with a string attatched. could i of had a miscarriage??
