Will this one class affect me even though I am passing all my other classes?

I’m a freshman in college and today is the final day of fall classes and a few minutes ago I just changed my major from journalism to communications liberal arts. Even though I’m passing all of my other classes such as mathematics,reading,and others, I’m very worried right now about this one class it seems I’m not doing really good at which is Public Speaking.From before it looked like I did pretty well then went down to almost falling below a C and this is the same teacher that doesn’t communicate with me nicely and has some type of attitude against me.

Today I came very late.She was going to mark an F but was still willing to give me another shot to probably boost up the grade so I did my powerpoint presentation along with my index cards.When I was done I was about to leave and she said to take back the cards because she said it was in some type of format she wanted it to be which I don’t understand since she never said anything like that about my index cards and she only said she’s going to give me an F on that one, not the power point.

When I went to the advising office, my advisor said honestly my teacher hasn’t done my grades yet so she doesn’t know if it’s going to affect me in anyway even though I’m passing my other classes.She said in her opinion that it shouldn’t affect me even if I am changing my major and I can still take my other new classes but it all depends on how my professor is hoping that I don’t have to take that class again.

Will this be any danger for such as with financial aid and other things? By the way, from a mail I got a few days ago I even got a letter from other colleges that they like my academic file and consider me to attend their colleges in the future.
