Pregnancy

I am in week 19. I feel tired easily and feeling so lazy nowadays. No mood to go to work as well. Been taking mc continuously from work. I know i should have not give in to the laziness but i just cant help it. Sometimes i feel like just leaving my job too. I cant sleep well at night been having bodyaches and keep on getting up to pee and getting up to work feels too much for me. Maybe i feel this way as this is my first pregnancy i guess. How you supermom do it? Working and going through it. Care to share how you supermom do it?
