This is a very difficult question, because, as you know, is absolutely harmless drugs not. Any medication has side effects, a list of which is sometimes very wide. And if a woman's body, in most cases without any unpleasant consequences to cope with these side effects, the fetus could end up much worse. After all, is still weak, but the emerging body unborn child is very sensitive to any changes in the biochemical state. And these changes are simply unavoidable when taking medication. Therefore, every expectant mother should keep firmly in mind and follow some rules.
During pregnancy, take the medication should only be a last resort, when it really is absolutely essential. If you can not (for whatever reason) to get medical advice, use only familiar to you, a certified drug. And in any case, be sure to ask whether it is not contraindicated during pregnancy and at least very carefully review the instructions attached to the drug. In your position better once err.
Take care of yourself as much as possible. Try to minimize the possibility of disease. If possible, limit your contact with people, do not hesitate to wear a surgical mask. Life and health of your unborn child is more important than puzzling and sometimes oblique views. Refrain from the use of exotic, unfamiliar food, especially with sharp spices, as it can cause a disease of the gastrointestinal tract, or allergies that require medication.
When medical examinations, consultations (especially in the early months of pregnancy, when the "interesting situation" has not yet been determined visually), you can assign any medicine. Be sure to ask again, ask if you can take it while pregnant. Shyness is not only inappropriate, but criminal. If you need to make some effort to clarify this question from an experienced specialist.
