Could I be pregnant???

I normally have my period every month, and this month is different. Its been a week now and haven't had my period. Me and my husband have been trying for a while now and I just think I need some advice. I think I spotted very little not even for a day, and then it stopped. I really want a baby and I really hope its true. My husband keeps talking about it and how excited he is, and how he can't wait! Idk though, I think I need a second opinion though!
