Miscarriage didn’t know I was pregnant

This happened almost 6 weeks ago.

I am 20 and on the nuvaring and had skipped my period for a month and I have skipped my periods before and it never caused me a problem. And mid cycle I had spotting for 2 days straight and I NEVER spotted in my entire life and I have been on the nuvaring for a year and a half. So I thought it was really strange that I spotted so I took a pregnancy test and it was negative. Then I thought maybe my period is just coming early, so I took out my nuvaring to get my period. I wasn’t getting my period and the spotting was on and off so I took another pregnancy test and negative again. Then Wednesday and Thursday I was in excruciating pain I thought I was having stomach issues (cuz I have stomach pain on and off like for 2 years- possibly ibs) so I just went on with life and lived with the horrible pain. I still thought my period was coming early cuz of spotting so I put a pad in on Thursday just in case I get my period. Thursday day I thought I got my period it was just an abnormal amount of blood. I thought maybe the pain I was having was cuz of my period maybe, but I never ever cramp on my period either. Thursday night the pain was only getting worse and worse, I never felt pain that bad in my life. I went to the bathroom randomly to pee and blood was everywhere I never bled that much in my life it was so scary. And suddenly a fetus came out of me, I bugged out! But my mind always goes to denial when bad things happen to me. So I almost convinced myself it was nothing. But deep down I knew it wasn’t. So I told my husband that I saw a fetus come out of me. I tried to make as it was nothing for that night but I was still in crazy pain. The entire Friday I was rolling over in crazy pain and was wearing a tampon and the thickest pad and it was still bleeding way too much it was going thru everything. Then I asked my friend who had a miscarriage what happened when she had hers, and she had the EXACT same thing happen to her (the spotting, then crazy pain, then the fetus come out) and the only thing different is that she was seven weeks so she knew she was pregnant cuz she saw a heartbeat. So then I asked my other friend who knows about miscarriages and things, and she’s like “you had a miscarriage it’s 100% miscarriage”. So I told my husband it’s for sure a miscarriage. He told me to tell my parents to ask what to do. So they practically forced me to go to a doctor. I finally went a week after it happened. The OBGYN was such a bitch. She didn’t even ask me what happened to me, she just saw written that I was here for a possible miscarriage. I had a panic attack in the doctors office. The only thing she did was told me to pee a pregnancy test and it was negative (obviously... because I came a week after it happened and cuz it was negative all along) So she says “okay we’ll never know” since it’s a negative. I was like “aren’t you gonna ask me what happened?”. She was like “well it’s a negative, soo...” I was like wow I didn’t need to go to a doctor to hear that. Besides the fact she yelled at me for taking my nuvaring out like wtf (cuz she had asked me my birth control method, and I told her the nuvaring but I took it out cuz of my situation) I am never going to that OBGYN ever again. And now the more I read about miscarriages (since it’s obviously on my mind) the more I am 100% sure it was one. And I never thought I would feel sad about it but i cried so much and I feel so so sad about it. Everyone keeps telling me ur intuition is always right, trust ur intuition. But I don’t know why I feel so sad about it since I didn’t even know I was pregnant just idk I really feel a loss :(
