I'm 8 weeks pregnant with number 2 and have been having mild cramps for the last week or so, this week they seem to have become a little stronger, more like a moderate version of 'stitch'... there's a constant feeling that something is a little 'off' in my abdomen. I understand cramps are actually a little more common in subsequent pregnancies than first ones (lacking in uterus tone or something that sounds equally judgmental!) and so I wouldn't be particularly worried except...
I have had pretty much NO nausea or sickness. With DS I was plagued with it, sick every morning and nauseous through the day. I've had slight feelings of nausea in the evening if I've been exceptionally tired, but nothing that even comes close to first time around.
I haven't, however, had any bleeding, which I'm hoping is a good sign, or at least, not-a-bad-sign.
If it was just one thing out of the cramps / the no-nausea, I wouldn't be as concerned, but both? Hmm. 
The other question I have is... with worries at this stage, who do I speak to? My GP? Or a midwife? You see, I haven't actually had my booking appointment yet (scheduled for just over a week away) so technically I don't have a midwife...
(Also slightly complicating things is the fact that ds(8) doesn't know about the pregnancy yet, so arranging a doctor/hospital appointment around the occasional afternoons he is at his dad's house wouldn't be easy (and my dh works full time)...I haven't told work yet, and it's really hard to get time off for dr appointments due to being in a school and it being the start of term. So if they did book me in for - say - an early scan, how quickly could they see me?)
Thanks!
