If you take a drug a few days before you get pregnant, the first thing to look at is what kind of drug you are taking and whether this drug has any effect on pregnancy. The drug is divided into four types of A, B, C, D. Type A is like a vitamin, there is no effect on pregnancy; type B will weigh the pros and cons, and generally have a relatively small impact on pregnancy; type C will have an impact on pregnancy, if necessary, may still choose to use, but the amount should be controlled; type D will certainly be irritating to the fetus, can not be selected. So first of all, it depends on what kind of medicine you take, because generally the drug description will be written above the pregnant woman caution, prohibited, prohibited drugs certainly can not be used; in addition, it also depends on the time to take the drug, in the end, when the period is just clean, or in the 2-3 days before the discovery of pregnancy, it will have a different degree of impact. Because it may be difficult for many women to get pregnant, or to miscarry after conception, the baby is very precious to them. Based on this situation, on the one hand, it is recommended that drugs must be chosen carefully, read the instructions and try not to use them because you are in the preparation period; on the other hand, if you have already taken these drugs, you can go to the genetics department for a detailed consultation if you are very worried. If there are no major problems, just try to strengthen the maternity checkups during the delivery period.
