Could I be pregnant??

So my youngest is almost 15 months old. I still nurse him in the morning and before bed. My period came back in March, I had 2 Normal periods. Now, my period is a week and it never is. I am so worried I’m pregnant. I am not on birth control and my husband wore a condom to finish each time, but sex without a condom right away. It seem like it could probably just be late because I’m nursing a little but honestly, I feel pregnant. Haven’t had a chance to get a test yet….so afraid of the result. Thoughts??
