3 weeks and 5 days pregnant

So I have 3 test that confirmed I am pregnant but went to the doctor yesterday and both test they did were negative. So frustrating the RN told me calculating I'm only 3 weeks and 5 days pregnant so it is normal to have a negative reading since it is so early so I decided to buy at my local dollar store and test at home today and I got this results below super faint lines which are hard to see... 😩 why won't this little peanut show yet lol... any other mommy's going through the same thing?
