Mood Swings = Pregnancy??

Y’all I feel so bad for my boyfriend. My family and I are having our house rewired and stuff so we basically have to pack up everything but a bed and maybe a dresser, which is alot for me. So I was a bit overreactive of that and angry. Then I started laughing at my anger to where I was crying. Then he had to go home and I started crying because of that. He had to stay 18mins after he usually leaves just to calm me down because I was crying so much. I don’t cry, but man mood swings just beat me with a bat. We think I’m pregnant so hopefully that’s why I’ve been so overreactive right now.
