Is it possible to have pregnancy symptoms 1 day after sex? i have been having nausia, dizzyness, headaches, bloating stomach, feels like passing out, hard to breathe, and bodyaches.

Pregnancy : Pregnancy symptoms (if due to pregnancy) don't occur unless you are already pregnant. The symptoms you described are very non-specific and could be pre-menstrual symptoms, and even symptoms of a cold or flu. If your symptoms have not resolved you should visit your doctor for an evaluation. Take care.

After : After fertilization, it can take up to 36 hours for the implantation of the egg in the uterine wall. Once the egg implants, your hormone levels begin to rise, which for many cause the symptoms of pregnancy such as nausea, breast tenderness, fatigue and dizziness, but this usually takes days if not weeks. More than likely, you are either pregnant from a previous sexual encounter or are ill. Having symptoms from pregnancy that soon would be highly unlikely.
