Two days ago I had a tan to brown discharge when I wiped, I used the restroom about 2 hours later and it was a light pink discharge, then 2 hours after that it was brown again. I was at work and all cell reception is cut off by blockers because of where I work so I couldn't look it up. But when I got home I had two more times of pink discharge and then nothing like I am really dry. I am in my fertile window could this be implantation bleeding or ovulation bleeding? The discharge wasn't enough to leak to my undergarments. I need advice my husband and I are trying for baby #3. I am sinking in different websites that say fifty million different things !
