HELP chemical pregnancy ???

So i need help ladies. i had what i thought was a chemical pregnancy this month. i had 5 positive pregnancy test and then i started bleeding last Friday. Got into my Doctor and got bloodwork done. She told me i was never pregnant and had false positive test. My question is do you think that is true? I was 3 days late when i started bleeding. So im just really confused and feel stupid if i was never pregnant. These are 3/5 that i took first one is 11dpo second is 13dpo and last is 14dpo
