5 dpo implantation bleeding? now 11 dpo faint positive hpt, pregnant or not?

Need a blood test: Home pregnancy tests are pretty accurate, with few false positives (unless you took a HCG trigger shot this cycle & there could still be HCG left from the shot). See your doctor for a blood pregnancy test (quantitative beta hcg). As it sounds like you're trying to conceive, take prenatal vitamins. 5 days post-ovulation is just before implantation, so discuss the bleeding with your md. Best wishes.
