Maglaba without washing machine

Mommies & mommies to be. I'm on my 17th week now. Nag wworry ako if i overwork ba. Minsan naglalaba kasi ako ng mga uniform ko and then I mop after since the floor gets really wet after ko maglaba. Okay lang naman po diba? Natatakot ako na baka may mangyari kasi sa baby :( Can this be considered exercise? Or too early pa for me mag exercise? Kaya minsan gusto ko mag maintain ng isoxilan/pampakapit. Huhu. 1st baby in 3 years, kaya paranoid ako hehehe
