So today I got this orangish/pinkish discharge. No I do not have any STD's. Or STI's. Could it be implantation? My last AF was 12 days ago. And I get my next AF in 17 days according to glow. Is it to early to get implantation? I already took a hpt and it came up negative. I'm thinking it's still to early to show up? How long should i wait to take another hpt?
