Gisela • Teen mom 💕
Girls I'm worried ! 😣😣😣 my period is late by 4 days now last time me and my boyfriend had sex was probably 2 weeks ago but last time I was late and my period came but idk what to think I hope I'm not pregnant, I'm not ready to be a mother. I want to go on birth control but I don't know who to call for it
