Ohh Sal ! I had shocking MS with my first as well ! I lost 6kgs ! all I can say is if you're not even able to keep water down to call your mw or go to the doctors as they may need to give you intravenous fluids but don't panic too much about not being able to keep food down, baby isn't big enough to need you to eat all the time at the moment.
Laura will be interesting to see how far along you really are !! do they do early scans where you are from ? with my first pregnancy like you I was sick from almost the day of conception (crazy I know but I was very ill) and with my second I didnt get any MS until 8 weeks and with my third I was sick from around 5 weeks ! so each pregnancy is definitely different !
AFM - My temp is doing things it doesn't normally do (as in it's never hit 36.8 before and it hasn't risen like it is, it tends to start dipping down towards the end) , I had spotting yesterday aswell at 8DPO BUT this happened last cycle too except on 9DPO, I have spotting for around 4 days before my AF arrives so I can't read into it too much. I'm in a really hard place cos I don't want/ shouldn't be getting pregnant but the other half still wants it really bad ! I guess it's not the worse place to be as I will be happy either way, it will be a massive relief if i'm not but i'll be super happy (albeit a bit scared) if I am ! It's hard not knowing how you feel though especially when it changes daily !
