Need help

I’ve been testing almost everyday since 9dpo and only ever got bfn. I am now 18dpo and don’t know what to think. Yesterday I posted a pic and someone said they might see a vvvfl on my easy@home test. So I went out and got a frer and used that this morning as well as another easy@home. Only been feeling very tired and have a dry mouth. Woke up today and felt constipated and not really wanting to eat anything (usually wake up starving). These are my tests from this morning. Does anyone see anything? Or know what else I should do other than wait??
