Hi all, first time on here - just wanted some thoughts/experiences on implantation bleeding? I'm expecting period on Friday, but have been having brown discharge all weekend and the last couple of days have been heavy cramping, brown discharge/blood (not enough to wear sanitary towel) With brown blueberry sized clots. Is this likely to be implantation bleeding?have taken pregnancy tests over last few days - all of which negative. Saw gp today who was very dismissive and said it's my period early but I don't normally get cramps or have brown blood with my periods! Anyone had anything similar? Had missed miscarriage back in December and anxious this could be embryo not sticking and body expelling.
