How to get past doubt

We have been trying for 3 months we did our first real insimination because I skipped a period and it didnt come for a while. But as soon as I ended my period we tried. I never tested positive for LH spike. I dont know when i ovulated. We did 4 inseminations this cycle. I feel pregnant I think it's my first time. I've been bloated, gassy, crampy, I had acne but it went away, I've had weird vivid dreams lots about being pregnant, I've been nauseous, heightened sense of smell , even my gums and teeth are sensative, constipation, and more. I'm currently, I think 10 or 11 dpo if my tracker is right. I'm getting negative tests for both pregnacy and ovulation. I'm worried I'm not pregnant and it's all in my head and I'm doubting and getting discouraged. I feel like I'm going crazy. Do you think I may be pregnant? If I get negative how do I cope should I keep trying? I got tests done my hormone seem to be fine and same with my blood sugars so we dont think I have PCOS according to my doctor.
