How long does it last? Possibly (TMI)

I've been bleeding and spotting for nearly 2 weeks now. I wasn't far along at all maybe 5 weeks. Around 8 last night (on my bday) I went to the restroom and I looked in the toilet and saw this long tissue like clot. I did take it out because I wanted to see if that way my baby. I believe it was there tissue looking thing with a blackish sac attached to it. I'm sorry if this is tmi but will the bleeding slow down now or how long did it last?
