Lotfancy pregnacy test

I heard these are not very sensitive and give really late positives so me and my husband are getting FRER tonight because we both think im pregnant. Im 4 days late today. Ive used like 7 boxes of these and have been trying for 4 years and never have we seen a positive. I might see a VFL but probably not. I will update with the FR. But i think lotfancy is a waste of money. I also chart BBT on FF and i think my odds look good.
