I am 27 weeks pregnant and am struggling a bit with life - terrible heart burn - no sleep - constant worry about the baby - it doesn't move much or I don't notice as so busy. I have a 2 year old and 3.5 year old and am exhausted - have just worked my 2 days back at work this week after having a holiday and it is a physical job and I have struggled with back pain and fanjo aching. Last night I had no sleep as felt like a hot coal was wedged in my throat. Up for day nowxentertaingvkids - DH out tonight so no help all day - can't face work tomorrow - so tired I can 't even be bothered to swallow my toast. BUT I am not in theory sick but would love to rest all day while DH helps out with kids! Actually I do know IABU but I need to lay down.
YANBU - You sounds exhausted and if you are not ill now you will be if you don't get some rest. Take the day off, put your feey up and see if you can help some help with the DCs etc so you can get a bit of sleep
kitkey if you are worried about lack of movements, please get checked. I know you are exhausted and have 2 little ones, but I think it would be advisable if you can to see your MW. You should rest and not go to work.
