Alright so me and my gf had sex november 19th. Shes on birth control, apri, but the condom broke...I pulled out, im pretty sure none got in her but I don't know....Her last period was nov 8th-13th...So it would put her ovulation date around the time we had sex...yesterday she said she has been tired since we had sex...really early for symptoms but I'm a pessimist. She also said shes had heartburn, thinking about food makes her sick, her uterus is hurting, she has a pain from her left hip to knee...she hasn't had any spotting or discharge...I think its her pmsing since her period is dec 6th but im still worried. I know bc isn't 100% effective but still.
