Why am im getting negative hpt?its been 19days after conception n i got a missing period,had implantation bleeding,pregnancy symptoms

Negative home test: It sounds like you are not pregnant since the home pregnancy tests are negative. What you are referring to as implantation bleeding was likely just an off menstrual cycle. Schedule a visit with an obgyn to confirm the findings and to discuss irregular menstrual cycles.

Blood test for HCG: You may see your doctor for a blood test for HCG level that is more sensitive and specific. Your doctor may also perform an ultrasound examination. Practice safe sex. Get HPV vaccine.
