Spotted

Hey Everyone

I just wanted to know if this happened to anyone. Late last night I saw a spot on my pantyliner that was small, kind of like a drop. Then the next time I went to the restroom, there were more spots but on the tissue this time, nothing on the pantyliner. They looked like two smeared small dots, smaller than the first one I noticed before. Could this be implantation bleeding or something else? My IUI was done June 30, the same day I had a positive opk, which would put me maybe 6-7 DPO, maybe 8. Later on today, there wasn't anymore spotting. I just don't know what those spots could have been. You guys think you know what they were? Sorry about the TMI, I just want to know.
