Can’t login to WP

Hi,
Really stuck here! I am pretty new to WP and had been using it fine on a PC to maintain my website. I then tried to login using a laptop I had used before and I couldn’t. I thought I might have got the password wrong so I reset it. Again, I couldn’t login. I have tried several times resetting the password and logging in but no luck at all. I am now thinking there is something wrong with my account but I have no idea what.
I run a small business and the website is crucial so any help would be great!
Many thanks
Sean
