18 days late, all BFN's but one test with a vvvfl that may or may not be an indent or me freaking out. No period symptoms but some bloating feeling in lower abdomen. Should I throw in the towel to assume the tests are right and I'm not or should I go to the doctor? Mind you my sister was the type to never test positive urine until really far along in her pregnancies with all 4 kids she had to have blood. Not sure if that's even something that sisters have similar traits on but throwing it out there to help.
