Thank you everyone for your support... so in the end my DH picked me up from work and I promptly burst into tears, and he insisted we called into the GP on the way home just to get their take on in. The receptionist fitted me in for a quick appointment.
Told the GP what had been going on, and she said the baby did feel low but that it was still bobbing in and out, but since I wasn't certain about the reduced movement side of things I'd better go to the labour ward to get checked out.
Off we trotted to hospital, at around 6.30. Eventually got in to an admissions room and hooked up to monitors around 7.30. By 8 I'd done the press the button when you feel a movement thing, and realised I probably was feeling plenty of movements, but had just got myself worked up. The trace was all fine, although contractions were dead on 5 and a half minutes apart.
We then waited until 9.45 for a doctor to come, all the time getting hungrier and feeling like a bit of a fraud, but eventually she came and when I said the only thing I could compare the pain to was when I MC'd she made me feel like I'd done the right thing. So got checked out, cervix closed, and have been swabbed in case of any infections causing the pain - which is probably a good thing in light of the thread.
I went home around 10.30, still with the cramps all round my back and lower abdomen, slightly worried that this would go on for the next 5 weeks. But I've woken up this morning and they've gone. So obviously something was going on and it's not just the typical pain I've got to resign myself to.
They're sending me for a doppler this afternoon just to check blood flow, but I feel so much better for the reassurance.
Only thing is it's made me want to be on the MLU even more - the admissions room was really grotty, and you could hear what was going on in the other rooms etc. I'm sure in the real thing I won't care, but I just didn't love it.
Sorry for mammoth update... thank you so much for the reassuring words ladies, you feel like a bit of an idiot causing a fuss, but on balance I'm glad I got checked out. Really want bambino to stay put for another few weeks, so fingers crossed.
Hope everyone else had a good and quiet evening, except unbuff who might be about to relinquish her place at the top... woopwoop. Will let you know how I get on with the doppler later (if I don't get snowed out of school... come on!!)
