Implantation bleeding

Ashley
While TTC I had sex all thru out ovulating. About a week after I noticed I had cramps on one side and light pink spot in my underwear. Two days later I had that one spot again and I've never spotted in between periods. I looked it up online and the color was exactly the same as the other women that got pregnant, the timeline in which it happened (7 days after conceiving it happens). I'm going to get a test? Do you think it's to early? I get my period in a week and a half? I feel bloated. Cramps come and go. This feels different. What do you ladies think?
Also, a photo online of a ladies implantation bleeding that looked exactly like mine I looked up and it turns out later on her forum she was pregnant. Same symptoms and everything. What do you think pregnant or not?
