my girlfriend is late on her period. shes graduating high school and its stressing her out. i my self have not yet graduated high school which stresses me out alot. the last time we had intercourse was may 3 and her periods usually start around the 16th-23. she seems to have the symptoms like cramps in her belly and her boobs are getting bigger as always idk about bloating though i try to never ask her about this stuff. there where no holes in the condom that i know of due to the air bubble the condom had after i pulled out. could the stress be whats causing the lateness?
