Congratulations :)
I think I'm around 7 weeks (midwife thinks more due to LMP date, but we'll have to wait for scan to know for sure!).
Started getting morning sickness about a week ago (just all day nausea, no vomiting thankfully). I've found Nairns stem ginger oat biscuits very helpful for the nausea and I don't normally like ginger much.
Also just discovered that roibos tea seems to help. It tastes like regular tea but is naturally sweeter/less bitter, it doesn't brew as strong so you might need 2 teabags to get a good tea flavour. It also doesn't have caffeine which is a bonus.
I've just found that puy lentils (aka lentille verts) are helpful for me too (probably because they're low GI), they're the small green lentils you can find in the whole foods section of Tescos. They need to be rinsed and then boiled/simmered for 1-3 hours, depending on how soft you like them. I like mine to turn into mush so cook them for 3 hours, then add olive oil, lemon juice, herbs and lot of salt :) Good way to sneak in some protein! I can only have a little at a time though, usually with some mashed potatoes. Lots of sea salt seems to help me with the nausea too. Most of my cravings are for salty foods! Today I want potato waffles and hula hoops :D
Fresh lemon juice in apple juice, diluted a bit with water is another thing I find helpful.
Fruit ice lollies help too, the coldness seems to stave off nausea for an hour or so.
Good luck! Morning sickness seems so individual, what works for one person may not for another!
