Give your sister a big pregnant slap!!! Ppl who have never been pregnant or have had easy pregnancies have got not the slightest clue about how difficult a difficult pregnancy can be. Maybe it's time to have a heart to heart with DH and be quite specific about how difficult it is for you. Tell him not to compare you with the other ladies because they are not having a "difficult pregnancy". You need his support & understanding now more than ever.

In the meantime, try to remember this is a temporary thing. Just because you feel like this this week doesn't mean it will last forever. And do whatever you need to to cope - get dinner delivered, decrease your work hours (or start your mat leave early - get a drs cert for this), rest more, whatever is going to work, just do it. You don't have to explain it to anyone, just do what you need to hun.

xxx Good luck.
