Have a Baby Already
Once you get married, your environment, friends, and particularly your parents and in-laws can add to the pressure to procreate. The additional pressure of getting pregnant would be needless stress if you were already attempting to conceive. Trying to have a kid is a strenuous activity that may take months or years.
When your mother-in-law becomes overly pushy, you must set a boundary somewhere. Otherwise, she will continue to push the issue. Some individuals may have no trouble conceiving; others may need time and error to succeed. During this period, be sure to surround yourself with good influences and avoid those who are adding stress.
