My girlfriend is on Rigevidon and has been for about 5 months. We always use condoms and I have never ejaculated inside her. Although we have undergone foreplay without wearing a condom and have slipped my penis into her for about 3 seconds before pulling out and wearing a condom. She does not miss her pills and has taken each one around the same time everyday as I recall. However, she is complaining of stomach pains, nausea, vivid dreaming and bad headaches. Could she possibly be sick, considering we are in the UK and are exposed drastic changes in weather and the flu, or could she be pregnant?
