Hey cysters I need some help (tmi picture in comments) so according to my apps I ovulated 2/4 but 2/5 I had a few drops of light pink blood and 2/6 I had a little more but only on the toilet paper. Is this implantation bleed or is AF on it's way never had this issue. Any advice would help thank you. Picture in comments.
