Hello doctors, I write in behalf of my female partner. We had unprotected sex on 16th July, without ejaculation inside. Her menstrual cycle varies from 30-36 days. Her last period was on 1st July which lasted till 5th July. On 3rd August,2021, she took a pregnancy test in the morning using the PregaNews hcG kit. Then she took a test on 5th August,2021 ,which came as negative and she had some blood in the evening ,which was brownish red. What does this suggest?Can we eliminate chances of pregnancy, or should we wait do another test? Looking forward to.
