TTC after nexplanon removal.... Help

Ok so my last AF was 7-17-15 got my implant removed on 8-06-15, no AF yet after removal, i have been tracking my CM this whole time according to my CM i was ovulating around 19th-21st and on 8-26-15 i checked CM and it was EWCM with a tinge of blood not bright red thought just enough to change the color of the CM and its been like that til today 8-28-15. I took a PT and it was really faint line on it... Could i be pregnant? Anyone has gone through the same thing and ended up being pregnant??? TIA
