about the cold, i would definitely not medicate until you see your doctor, but for aches and pains tylenol is ok (if your doctor says so). as for the no appetite and sleepiness, #1 could be from the pregnancy, as we get bigger our poor stomachs run out of room for food rendering us without the sensation of hunger. and as for the fatigue, you are carrying on the extra weight, and your metabolism is working overtime to make that beautiful little baby. #2 these are also signs of depression (without or with the pregnancy), so combine the discomforts of pregnancy with the sadness of not working etc and it is understandable. talk to your doctor.
PS i KNOW where you are coming from. i myself and prego for the second time (my son is 21 months old) and this time is with twins. i am 35 weeks and miserable!!!!! back ache, fatigue etc, none of which i had with my first. i am also pretty bummed about not working. lonely i guess. all of this normal from what i am told,hormones and all. just try to keep everything in perspective and remember what is at the end of the yellow brick road... a beautiful and healthy baby! good luck, email me anytime you want to vent!!!
