Another lurker finally daring to post. I'm 10+1 by my dates (11+1 from lmp but with a 5 week cycle) with dc1 after 2 MMCs in the last year. Had my booking in a few weeks back, scan is next Weds (glad they book those on their dates!), a little worried as only then will we know for sure this one's stuck but the nausea and burping are providing excellent reassurance!
I read 50 shades 1 on holiday in September and really enjoyed it, read the other 2 when we got back because I wanted to see what happened to the characters but it wasn't the same when not on a sun lounger. That would have overlapped with conception but post- holiday relaxation had a lot more to do with our success.
With my first pregnancy we told my parents early on (staying with them, couldn't hide not drinking, already a little bit concerned though and they were fab), I told a couple of friends, then when the MMC was confirmed told my boss, my sister and auntie (the latter was staying with us at the time), and a close friend who is a GP so was very supportive with medical facts during natural management. Afterwards told inlaws and a few more friends who I knew would understand when related conversation prompted it.
Pregnancy 2, 1 close friend knew before, she was newly pregnant so we traded news. Then I went on a hen do, told the bride and a couple of others, the rest guessed but didn't talk about it. Told my boss when I was referred to EPAU and my sister when it all kicked off, then parents etc. I think first time was easier as my Mum was amazing, just the right balance of supportive interest and helping distract me when there was nothing I could do. Unfortunately second time my parents had other crises to deal with so it didn't feel right to burden them with more worry until I had to.
As things stand today, my parents, sis and BIL all know, as does my boss (has been v supportive of working from home 1 day/wk), 1 very close friend, and a friend at work with similar dates. Avoided telling inlaws at 6 weeks so hopefully they will get exciting news on Xmas Eve.
So summing that up, I think it's good to tell people who would be supportive in a MC scenario (in a way you could cope with, MIL doesn't know because she'd be overbearing), or who can help now (eg an understanding boss), but don't risk the blabbers if you can help it!!
Sorry for a v long post. And in all that I've not said - my dates = July 11th, mw dates = July 4th. Will find out on Wednesday!
