Could this b true

So i received a phone call twice from my mother (this us usual, I'm a college student) this morning questioning my well-being. But she was saying things like "how's everything with you and your boyfriend?" "Do he want a baby?" After I answered those questions we departed off the phone because she was eating a sandwich, then he calls and says.."Baby i think you're pregnant!" my phone's ringing on the other line now. Its my mom laughing explaining that she cant stop eating her stomach feels like a bottomless pit. While she's ordering tacos from taco bell. She tells me I'm a month pregnant. I'm shocked because my breast are swollen, my nipples are so sensitive it hurts to even wear a bra. Lastly my pants are tighter, I belch. 24/7 I puke everyday (weather it a lot or the kind that just comes up while belching or talking). I'm breaking out all over my face and my boyfriend and I heads hurt like bad migraines. Could my mother really be getting these weird cravings because I am pregnant?
