Tammy 💜👼🏼

Mama’s in need of some advice!!! The sex we had in the 2nd hubs was buzzed and and is unsure if he pulled out in time.. so here we are a negative test as of yesterday afternoon and no period still.. yesterday I had wiped and had some brownish discharge.. and later in the day some light pink blood when wiping but nothing today.. my period is usually on time or early.. has anyone had this happen and not be pregnant. I’m not ready for another baby. She’s only 15m
