Ladies i am sooo confused 😭 tuesday i had what i thought was implantation bleeding.. was very pale pink . Only was there for one whipe. Last night i went to feel my cervix with toilet paper. The outcome was mucousy and brick red. I wiped a second time it was mucousy and brown. Wore a tampon to sleep last night. Woke up around 8:30am to change it and it was dark brown w/ some bright pale red.. period was due on the 17th. If this is a “late af” , my flow would have started by now.. what’s going on? Have u bad same experiences and what happend?
