It was only one poster who said early tests were self indulgent. I certainly don't agree with it but I don't understand why it's getting so many comments - it's derailing the more interesting aspects to this thread.
Please note I wouldn't say the following 'out loud' as I know it's delicate and could upset other people. However, I think my opinion is of interest on this thread and I hope it contributes to the discussion.
I'm 'old' and I miscarried my first pregnancy when I was about 12 weeks pregnant. I hadn't told anyone as I was waiting to see if the pregnancy had 'stuck'. When I miscarried I was upset as I was disappointed but I didn't consider that I had 'lost' a baby. I took it that the embryo wasn't developing properly so what I had lost was an opportunity to have a baby rather than an actual baby. I never grieved a baby as I didn't consider one had exsisted properly. Either my body wasn't ok to carry the embryonic matter or the embryonic matter was not viable. Iyswim. I fully understand that is not how some other people view it so I wouldn't dream of saying that normally.
Once I had miscarried I told my friends and coworkers and had nothing but support. The women and the men at my work were sympathetic and no one said anything inappropriate. Lots of people said that they had experienced the same thing which made me feel better. It certainly wasn't a taboo subject. I felt It was something to be sad about but not something to be devasted about. It felt like it was a normal thing to have happened. I thought it was all dealt with in a very healthy open way which suited me. I had to have a D and C (I think it was...can't remember really) and I had a cry in the hospital and the nurse couldn't have been sweeter. She was lovely and gave me a wonderful hug that I remember to this day. I was clearly told that it was normal that some women could feel very upset and I was given a leaflet with information about where I could get help from. There didn't seem to be any expectation about there being a correct way for me to behave.
I know that if it had been a later miscarriage or still birth then that would have felt very different. I also think that if I had had multiple miscarriages then I would have been far more upset.
Given the fact that so many women miscarry I'd find it hard to imagine that women didn't talk about it among themselves. Maybe the discussion wasn't quite as visible as it is today with Facebook etc but I'm sure it was there.
I guess what I'm saying is that I would agree with your group of older friends about being cautious about a pregnancy until you have missed a couple of periods. However, I wouldn't dream of being dismissive of anyone who was upset about an early miscarriage. I'm actually suprised that they said that 😳
If one of my daughters were pregnant and asked my advice I would encourage them to be a little cautious at the beginning. I think that would be sensible. Pregnancies are long so holding back a little on the excitement front at first isn't unrealistic.
One thing that I've noticed on many Mumsnet threads is that many women who are struggling with a miscarriage find it difficult to talk about their feelings with friends and family. This means that friends and family have to guess how to approach any difficult situations. For example some people want to acknowledge anniversaries while others don't want to. I think it needs to be easier for women (and men!) who are grieving to be able to talk about what they want. I don't see that that side of things has improved from when I was young. At least not going by what I read on Mumsnet.
