Having a cold in pregnancy

Faye • Twin mum and expecting my 3rd.
Has anyone else felt ten times more ill during pregnancy?? I'm a teacher and have caught a cold or something from my kids which I would normally power through but I'm just a mess!! I'm only 8 weeks and worried I'm not going to be able to do my job properly if a tiny cold has knocked me so badly so early in my pregnancy!! Can anyone recommend anything safe to take other than paracetamol??
