Hi I gave birth on May 18, and have been having unprotected sex, about 6 times since then. I am breastfeeding . I just took a pg test, and it showed a very faint positive (I was going to pick up my birth control tomorrow, and jsut wanted to take a test to be sure, as directed by my midwife). Could it be that it is a false positive, hcg levels just left over from my pregnancy?
