Feeling crazy

Last period August 4, 41 days ago. Have never been late. Urine tests are negative. Have little pink when I wipe. Stomach feels full, that being said I've had kids and never had any nausea or pain in pregnancy. Doctor wont see me. What if I missed period having chemical pregnancy that's why urine is neg but I feel pregnant? I had a missed miscarriage in April not 6 weeks along.
