As I have understood now you are taking tri sprintec
so the probability of getting pregnant is very low. Concerning your health it depends on your previous problems. If you had cardiovascular pathology or intestinal or liver
problems the overdose can complicate these diseases. However if you are generally healthy do not bother. All will be ok. Try to avoid much physical activity and be careful to your diet (avoid much fat and alcohol).
Wish you Good Health
