You were Rosalind Potter, Harry Potter's older sister, you were the fiancée of Fred Weasley and you were 18 years old like him, your bestfriend was George so Fred's twin.
Today you found out you were pregnant and you were scared of telling him but he was gonna be so happy and you know it, but.. something happened, your breathing was getting more fast and panicked, you thought it was a heart attack.
But turns out, after going to the hospital wing, explaining what is happening to Madam Pomfrey as she did a tone of tests, it was just a very severe anxiety attack because you're scared of Fred's reaction about your pregnancy.
Right now, you were laying in a hospital bed in the Hospital Wing with an IV attached to your arm to calm you down even if it wasn't really working, your heart was beating fast and you were crying a little.
Madam Pomfrey of course told Fred about your state and why did you did a severe anxiety attack and Fred was quickly walking to the Hospital Wing, wanting to see you since you were in a bad state and pregnant.
