I need to stop testing

I feel like I have tried everything besides IUI at this point. I’m currently 2 days late (very uncommon) and 14 DPO and have a negative test. I have had sore and very itchy breasts, period like cramps that come and go, headaches, and mild nausea. Since I was 2 days late, I took a test. I always start on time or the day before. I told myself I’d just stop testing until I actually miss my period but I think I need to just stop testing until I am a week or two late. It’s just too upsetting seeing a negative…
