Emotional roller coaster

Ala

On November 4th, after 8 days of my missed period I took a pregnancy test and it was positive. I was surprised. Although I’m not on birth control my husband and I do natural family planning and didn’t think we had slipped up lol. This is our 6th pregnancy. 4 alive and healthy, and one missed miscarriage 2 years ago. A few days after a positive test I started having some mild cramping and on Wednesday randomly while at work I started bleeding quite a bit through my underwear and jeans. I was horrified when I got home, and assumed I was having a miscarriage. Later that night there was no more bleeding just some spotting when I would use the restroom, but I had horrible cramping for the next two days until Friday when I couldn’t take it anymore and I finally called the doctor they recommended I go to the ER so I did. There they did blood work and an ultrasound. When the results came back they said my HCG levels were pretty high and they confirmed seeing a baby but sent me back to the woman’s clinic to talk to a doctor there. When I get there the doctor tell me my levels don’t match the size of the baby and there wasn’t a readable heartbeat, so she’s pretty certain it’s a miscarriage and we can discuss options to help it happen faster. 😡😳 I asked if there was still a chance it can be viable and she said a small one but she doubts it but we can check my levels in a few days to see if they go up. So fast forward a few days and my levels have went up and my cramps have subsided and the spotting has stopped. So now the doctor said she’s surprised but still can’t call it viable and wanted me to go get another ultrasound. Then this morning there was blood in my morning pee and I had mild cramps again. So now I’m waiting to go back for my ultrasound but I just feel so confused. Wondering if anyone else has gone through a roller coaster like this as well.
