Miscarriage at 6 weeks or??

This is tmi but I really need some opinions and answers from women that have gone through this type of thing. For about 2 days now I have been bleeding, yesterday I had a tiny clot that I thought was a miscarriage but today I have passed two giant clots which will be in the comments, I really want to know wether any of these could be my baby or even if it’s a miscarriage. This didn’t start happening until I had entercourse the night before it started happening, I just thought that my bleeding was because of my uterus being sensitive or what not, please tell me what you think. It’s Saturday as of today and Monday morning I will be calling to be checked. This is also my first pregnancy.
