How to reject "invalid" input in Python3.7

[Bruizeh]

I see an indentation error there. You have to be careful with the indentations.

Try this solution

while True:
    try:
        height = float(input("Input your height in meters: "))
        weight = float(input("Input your weight in kilogram: "))

        userBmi = round(weight / (height * height), 2)

        print("User BMI: {}".format(userBmi))
        break
    except ValueError:
        print("Incorrect, Try again")

Hello, your solution worked, thanks!
However, (sorry) I have stumbled across another issue. I tried to replicate what you did with my other input questions but when I tested it with invalid input it simply continued, here is the section of the code that I have issues with.

userPreg=input(" Have you recently been involved in sexual activity and thus are now pregnant? Yes or No")
if userPreg == "No":
    pass
elif userPreg == "Yes":
    print("You're too active you testorene filled homo sapien")
    raise SystemExit

How would I implement something similar in this scenario? Sorry for bothering you
