Iam a 45yr married female who is trying to have our 4th baby. i have PCOS and have had 3 full term pregnancies with no complications. my june cycle was scheduled to start 6/18. we tried to conceive. my cycle started early on 6/11 with 4 days total of bleeding. the bleeding started light, then heavy then ended on day 4. my question is could this have been implantation? i experienced no cramping during this bleeding.
