Is it Normal?

I think as long as you and your husband are conscious of the fact that while you are a student you will need to keep yourselves under control, things will be fine. Then inshAllah, you'll do well enough to have some of the luxuries you want. You're only 22 afterall. Very few people are settled completely at that age.

There will ALWAYS be people making comments. If you work, you don't work, you have kids, you don't have kids. Paying attention to those people isn't going to please them and it will just make you miserable. Ignore them and do what makes you happy.
