Gummi, am back on certirizine/zyrtec (1/2 a tablet a day is all I need). The doc (not my regular one) prescribed me phenergan (sp?) when I went in to say I was pregnant. These made me really sleepy but I persevered until the consultant at the hospital last week said it was fine to go back on certirizine; my regular doc okayed it this week. I don't think it matters that I take them for urticaria (itchy skin condition) than hayfever - it's the same drug. And I don't know if a factor was that I'm past 12 weeks. But life has improved HUGELY since I went back on them! I know you can't take my word or the word of my consultant but perhaps you can investigate further / get some more medical advice? I feel for you?
Panic, I'm sure if it was something to worry about the MW would have said, and your bean is clearly very happy in there! 20 week scan soon, anyway, so try not to fret too much 
Glad to hear of your excellent NT results, Backward! Hope you had a good OU tutorial to take your mind of the stress of the day 
Ah yes Zoey I remember now about your difficult situation re MIL?agh, my heart goes out to you. Not at all easy. Glad you're back home and enjoying it!
Sounds like a v.g. plan re help with cleaning Three ? and the naughty part of me wonders aloud if you can't just say to MIL something like 'I'm really sorry if I come across as a little less tolerant than usual this weekend but I'm sure you can understand that the tiredness etc from the pregnancy is taking its toll and I'd really appreciate your patience with me' as a bit of a warning that she had better be careful with her sarcy comments! Too much, maybe? I'm always straight up with people TBH and not v.g. at tolerating difficulties without just saying something! (This isn't always a good thing!)
Enjoy Devon Ethel!
Vivee, sounds like a tricky moment when everything is taking off professionally yet baby is coming soon. I'd recommend trying for a new job regardless. You might get some go-ahead firm who are fine with the mat. leave. Or do you have opportunities for freelancing which could work around baby more flexibly? I'm sure it's not at all impossible to re-launch self in a year's time, but it might be sensible to try to capitalise as much as poss on the energy and drive (and time!) you have at your disposal now?
Nightnight all
