I swear this tww is the hardest

I am currently 7dpo. ive been trying not to symptom spot and cervix check but I can’t help it. My cervix always drops super low straight after ovulation. It dropped low and then about 5 days ago went high and soft. Yesterday it was high and super closed. I also woke up yesterday with terrible stomach cramps like gas but I didn’t have gas. And a sharp stabbing pain that made me shout out. Today I have the same pains but milder but my cervix has come down a bit and feels more open. Now I’m adamant I’m not pregnant and I’m crying like an idiot. Why don’t they make super early pregnancy tests that can tell you straight away 🙄 it would stop a lot of crazy women from stressing for 2 weeks.
