Hi guys! So yesterday I thought I saw a little bit of pink when I wiped but thought my eyes were playing with me. We'll this morning I went to class and everything used the restroom saw nothing , about 2 hrs later I went back and saw this (look at the pic) it's a mix of pink and brown. It's only a little and that's all there is. No more blood. I checked down there to see if maybe it was a cut or something that was bleeding and got mixed with my discharge but no cuts or any external bleeding. My period was March 9-15th. My fiancé had sex on March 15th, 21 and 22. My ovulation (by calculating and calendar) should be anywhere from 21-28. Could this be implantation bleeding?
