Is there a such thing as looking pregnant?

Sooo my period was 4 days late this month and my period was unlike any other. I was bleeding on and off and had more brown blood than regular. I have read about implantation bleeding but my period was on and off for 7 days. I’ve actually gained 6 pounds and i haven’t been eating more or doing anything more than i usually. I haven’t tested bc i always get so stressed considering I’ve been ttc for two years. So i posted two pics for help to see if I’m just gaining weight or may be pregnant.
