I'm confused about my period

Elizabeth

here's the thing I had a period end of August but no period in September at all! I've gained a few pounds my belly Is round but I can't tell if I'm just bloated or I'm pregnant! idk when would be a right time too start taking a pregnancy test :/ my period isn't on track anymore for some reason I just don't know if I'm really super late or pregnant :/ I've been feeling really nauseated and tired but that's about it! And cravings
