pregnancy tests

eileen
So i recently took a pregnancy test 2-3 weeks ago and all 3 of the test came back postive. 4 days later i took 2 (dollar tree pregnancy) tests that came back postive as well. i was having pregnancy symptoms and all and then i recently stopped having symptoms and took another (test clear blue) and it came back negative 🤔 so confused on why it would come back negative and i did not have miscarriage symptoms at all!
