anyone else pregnant and have this problem walking to work! 😷

I am 22 weeks and I don't drive as of yet I walk to work takes me probably about 25 minutes and it's down a long road / hill and I. Literally sweat so much!! I have to bring spare underwear with me ( bra and knickers) cause they get covered with sweat it's horrible am I the only one this is happening to? I'm not over weight or anything just pregnantÂ
