Please I need help!!! 😩😩😩

Who’s pregnant and had a late ovulation then got bleeding but then tested positive... I ovulated on CD 21 on CD 35 I bleed and yesterday was the last day on CD 32 I tested and had a negative. Well for the past few days I’ve been having sensitive sense to smell it’s weird because I’ve had that with my other children but always tested positive 🤷🏻‍♀️ I decided to test today which would have been CD 40 and got this 3 different test.......
