I’m late on my period but haven’t tested yet

I’m late on my period but haven’t yet tested, I’m really worried to test I’m currently under the fertility clinic following 10 miscarriages and chemical pregnancies. I haven’t started any treatments yet and am still awaiting results to find out why this has been happening. I’m really worried if I’m pregnant again it’s just going to be more upset and heartbreaking. My mind is saying not to test as if I do and it’s positive It won’t stick but another part of me is wanting to know. Any other women been in this situation? I feel so low and it just isn’t how I expected I would feel I’m just so unhopeful. Is this normal to feel this way?
