My girlfriend and I have always been safe about sex. We use pills and condoms and she has taken them every day this month except for in the beginning. She missed the first day and took two on the second after her period. We have had a lot of sex this month, and have had a time where the condom did slip a bit (not a lot) when removing after ejaculation. About a week and a half after her last period she began to have backaches, headaches, and neck aches, as well as nausea and a fever. She also has had subtle food aversions and mood swings. We are now 5 days from the end of this pack and she says she feels like her boobs have grown... I know I may be freaking out too much, but it just seems like a lot of symptoms to be having.. Could you help me out?
