On the 21st of November , which also happened to be the day I was at peak fertility and ovulating . I had unprotected sex. He claimed that he “pulled out” however , I am having my doubts about that claim. On the 25th , I had this discharge 4 DPO. My period isn’t supposed to start for another 1 in some change. I’ve taken two pregnancy tests all have been negative so far but many have told me that it may be too early , thus, I am getting false negatives . Could this possibly be implantation bleeding?
