Trying to stay positive but I think I'm losing pregnancy number 8.

Im 6w3d today and I've been having mild cramps since I wad about 5 weeks, but today I got super stressed out. I got into an argument with my partner and he screamed at me and walked out, slammed the door and wouldn't speak to me for several hours after that. I broke down crying hysterically when he walked out and then the pain started about 2 hours later. They're not the same mild cramps that I've been having, these are sharper pains and they momentarily catch my breath and its really sharp until it eases off again. My next scan is Tuesday, but I'm convinced this is the beginning of my 8th loss. I'm heartbroken and angry with my partner, he knows how high risk we are and that this is the furthest we've gotten in our pregnancies. There's no real reason for this post, I just need to put this somewhere. If anyone can provide any comfort or opinions on the pain, then I'd appreciate that, but I know no one can really settle my mind at this point so I'm just stuck here in my fear and anxiety and pain for the next couple of days I guess.
