Advice needed! Anyone used these tests and had the number drop?

According to my ovulation day I'm 5weeks 4days today. I took a digital weeks indicator test on 3rd November and it said 3+ weeks, then all say yesterday I've been having off and on Cramping pains and this today said 2-3, so my hcg is dropping in my urine.

I've had 6 miscarriages. Please can anyone give me any words of comfort or help? I have a vaginal scan tomorrow but I'm so so scared to go in and be told that I'm miscarrying again.

The pains are almost unbearable but I haven't started bleeding yet. I'm 99% sure I'm miscarrying but I'm desperately trying to tell myself that it might still be okay.

Has anyone else had this happen and gone on to have a healthy baby? I'm trying to convince myself that maybe the tests are super temperamental, but the pains are telling me it's probably another miscarriage starting.

I'm so heartbroken and done. I think I'll have to stop and just accept it after this, the emotional toll is just too much.
