Miscarriage..?

So pretty sure I just had a miscarriage...I got the depo shot about 6 weeks ago but hubby tried a couple days too early I suspect. I started slowly bleeding yesterday and then this fell out when I went to the toilet earlier. My cramps have increased and bleeding is bright red. I’m 14 weeks post now and really didn’t want a sibling so close. I don’t know how I feel tbh..
