Worried!

Vicky

Hey, just after advice/thoughts... I’m about 5/6 weeks pregnant.. today I have had quite a lot of pain which has felt like period pain.. it lasted approx. 2 hours and in that I had a small amount of brown discharge... none since. I panicked and took a test which came back as not pregnancy 🙁.. My doctor didn’t seem too concerned as there wasn’t much bleeding and the pain has stopped.. but I’m confused by the negative test ( I’ve taken two before which were both positive)... I have drank quite a lot today?!?!? Just wondering if anyone has experienced anything similar?? Thanks
