Frustrating and confusing....

So my husband and I decided to start trying for a baby, since he is in the military he can be deployed at any time. There’s nothing more important to me that having a family with the love of my life. For the past 2 weeks I’ve been throwing up every night around the same time, I was supposed to get my period on Friday and I still haven’t gotten it. I’ve taken a test and it was negative, I’m going to get more today. I get so worried that there’s something wrong with my eggs or his sperm. I feel alone in all of this, I know I have my husband here but it’s just hard because everyone I know is getting pregnant, and it just makes me want a baby more. Should I keep testing?
