Dollar store pregnancy tests?

So, 6th month of ttc and no luck yet but I'm kind of sick of spending $12 on tests that will come out negative . Are dollar store tests accurate ? I heard they take more hcg to show up then normal but are they worth it ? Obviously if I see a line pop up I'll invest in buying a higher end one to confirm but until then I think I'm done spending almost $30 in pregnancy tests every month 🙄 let me know your experiences w them and tyia!💕
