Confuse

So my birthday day is coming up 8/5 . I’m going to turn 29. I’m going on a trip pretty soon. I Live with my husband just me and him. We both work. We both have to commute together we work about an hour away from our home. Lately my job has been stressful. There so much changes going on at work (let’s keep in mind that I work in a senior living home with dementia residents). Me and my husband would like to have some kids one day. but we are not trying to get pregnant.but then again we’re not taking care of ourselves we see it as iif it happens it happens. I never been pregnant I never been regular on my period . I was taking birth control to regulate my period.But the moment I got married I stopped taking them. My period does not come come every 27/28 days. But I do get my period every month. This month of July has been different I don’t know because of the stress at work or because I’m very excited for my birthday or because I’m going on my trip. But my period did not come this month and my nipples were sore for a week actually there’s still a little sore. And I feel a little emotional like for example today I feel lonely that I started crying and that went running to my husband telling him that I felt lonely. I don’t know if I should take a pregnancy test because I’m thinking it’s too early and that is stressing me out even more. And is making me sad . I just don’t know what to do . I really don’t want to tell my husband that I am thinking I might be pregnant because I really don’t wanna get his hopes up for nothing. Now that I remember I did have spotting maybe like two days and I thought I was going to get my period because usually when I start my. I get really really bad headaches and that happened to me but my period Never came.
