Freaking out..

I’m 6wks 4days today. I went in last week for an ultrasound due to some sharp left lower abdominal pain, they didn’t see much and told me to come back in a week. I went in today and got another ultrasound and saw my baby and heartbeat with a rate of 122 even got a picture. At the appointment after my ultrasound my doctor finally told me the ultrasound tech was worried about placement at the last ultrasound and equally worried this time as well, I was confused as no one said anything to me. She said looking at the ultrasound everything seems fine but when they look at it in 3D it looks like the baby is growing where my fallopian tube meets my uterus so it might be a very weird kind of ectopic pregnancy but they aren’t sure… they said where it seems like it’s placed the baby would be growing near the opening of the tube but surrounded by muscle if that’s the case it won’t be a successful pregnancy. But they said they can’t be sure, they are sending me to the hospital for another scan next week for a fresh set of eyes (there words) I’m freaking out. This was a very unexpected unplanned pregnancy. But now seeing my little bean and a heartbeat I’m truly devastated at what might be the outcome. Just looking for some positive thoughts. This next week is going to be beyond hard.
