It's been 7 days since i ovulated. 3 days ago which was the third 30th of October I had brown discharge also known as spotting. First of October I had pinkish reddish spotting then Brown. 2nd of October I had brown discharge and cramps on the right side and lower back pain. I took a pregnancy test and it came out negative I am sure it's too early but does this sound like implantation to you ladies?
