i am 15 weeks pregnant, i work as a cleaner ... im doing a lot of lifting and bending and here in australia its coming into summer and today its been soooo hot like 98 farenheit! I am also a mum already for 4 other kids. im finding my work is really taking its toll. i fell over today i was that dizzy and my back hurts and im getting braxton hicks ... i see my midwife tomorrow not sure if i should mention it to her ... i havent told work im pregnant yet as im sure my boss would fire me or not. by law im meant to get light duties but shes a bit of an old dragon..... i just worry that ill do harm to the baby by all this lifting nd working ... can i harm the baby?
